Product Details

310 SS plate is the common abbreviated way to describe Type 310 stainless steel plate. In technical purchasing, however, the abbreviation alone is not enough. The order should identify the exact grade, material standard, thickness, width, length, surface condition, supply condition, and quantity.

For quick reference, heavy-gauge plate is commonly requested in the 3–50 mm range. Common commercial dimensions include 4 × 8 ft, 5 × 10 ft, and larger project sizes such as approximately 2 × 6 m, subject to production capability and availability.

Fast answer: “310 SS Plate” means Type 310 stainless steel plate, but a formal RFQ should say something like ASTM A240 310, 10 mm × 1500 mm × 6000 mm, specified surface and annealed condition. If 310S is acceptable, it should be stated separately rather than assumed.

310 SS Plate: Abbreviation Meaning

“SS” is simply an abbreviation for stainless steel. Therefore, “310 SS Plate,” “310 stainless plate,” and similar search terms generally refer to the same basic product category: Type 310 stainless steel plate.

Search language is often shorter than purchasing language. Engineers, fabricators, and buyers may use abbreviated terms in emails or online searches, while a purchase order needs enough information to prevent grade or dimensional misunderstandings.

Quick Specification Card

Item	Quick Reference
Grade	310 / UNS S31000
Product	Stainless steel plate
Typical thickness	3–50 mm
Common format	4 × 8 ft
Larger format	5 × 10 ft
Project-size example	Approximately 2 × 6 m, subject to supply capability

Dimensions shown above are common reference ranges, not a guarantee that every combination is available from stock. The exact size should be confirmed against the supplier's current production and inventory capability.

From Abbreviation to Formal Order

A short inquiry such as “310 SS plate, 10 mm” leaves several important questions unanswered. A formal specification should convert the abbreviated request into a complete material description.

Abbreviated Request

310 SS Plate

Formal Order Example

ASTM A240 Type 310 stainless steel plate, 10 mm × 1500 mm × 6000 mm, specified surface, solution annealed, required quantity.

This format makes the material easier to identify during quotation, production, inspection, packing, and receiving.

What Should Be Included in the Order?

For most industrial orders, seven basic fields are enough to turn the search term into a useful purchasing specification.

Order Field	Example	Why It Matters
Grade	310 / UNS S31000	Defines the material chemistry
Standard	ASTM A240	Defines applicable product requirements
Thickness	10 mm	Controls section size and weight
Width × Length	1500 × 6000 mm	Defines the delivered plate format
Surface	No.1	Controls surface condition
Condition	Solution annealed	Clarifies delivery condition
Quantity	10 plates	Allows accurate stock and production planning

Solution Annealed Condition

310 plate is normally supplied in a heat-treated condition appropriate to the applicable specification. For many procurement documents, solution annealed is used to describe the intended metallurgical delivery condition.

Solution annealing helps restore the desired austenitic structure and reduce the effects of prior thermal processing. The precise heat-treatment practice and cooling requirements should follow the applicable material specification and manufacturing procedure.

If the plate will later be welded, formed, machined, or exposed to another heat-treatment cycle, those requirements should be considered before ordering.

310 vs 310S: The Ordering Mistake to Avoid

One of the most common purchasing problems is using 310 and 310S interchangeably. They belong to the same high-chromium, high-nickel austenitic family, but their carbon limits are different.

Standard 310 allows a higher carbon content, while 310S is the low-carbon version. The lower carbon content of 310S is particularly useful for many welded structures because it reduces the tendency toward chromium carbide precipitation during welding and associated thermal exposure.

Point	310	310S
Basic designation	UNS S31000	UNS S31008
Carbon	Higher permitted level	Lower permitted level
Welding	Requires an appropriate procedure	Often preferred for welded fabrication
High-temperature strength	Strong	Generally lower than higher-carbon variants at elevated temperature
Order description	Specify “310”	Specify “310S”

Never rely on “310 SS” alone if the distinction matters to the design. The exact grade should appear on the quotation, purchase order, packing documentation, and material test report.

How to Check the MTR

The material test report, or MTR, should be checked against the purchase order before the material is accepted. The grade designation and chemical composition are particularly important when distinguishing standard 310 from 310S.

MTR Verification Checklist

Confirm the stated grade and UNS designation.
Confirm the applicable product standard.
Compare reported chemistry with the specified grade limits.
Check thickness, width, and length against the order.
Verify heat-treatment or delivery condition where specified.
Check surface condition and identification markings.
Confirm the quantity and heat or batch identification.

This simple comparison can prevent an incorrect grade from entering fabrication, particularly when both 310 and 310S are commercially available.

Common Ordering Errors

Error 1: Grade Only

“310 plate” does not define thickness, dimensions, surface, quantity, or applicable standard.

Error 2: 310/310S Mixing

The two grades should not be written as though they were automatically interchangeable.

Error 3: Missing Condition

If solution annealing is required, the delivery condition should be stated clearly.

Error 4: No MTR Check

Receiving inspection should compare the MTR with the purchase specification before fabrication begins.

310 Plate Stock and Quick Inquiry

For a fast stock inquiry, buyers can use the abbreviated term initially, but the request should quickly be converted into a complete specification. This helps the supplier determine whether standard stock or production material is the better option.

Fast RFQ Template

Grade: 310 / UNS S31000

Standard: ASTM A240

Size: 10 × 1500 × 6000 mm

Surface: No.1

Condition: Solution annealed

Quantity: Required number of plates

For urgent requirements, include the required delivery date and whether equivalent sizes or 310S are acceptable. If substitution is not permitted, clearly state “310 only” and require grade verification on the MTR.

Commercial Supply Support

Teda Ganghua supports industrial buyers sourcing stainless steel products for thermal equipment, furnace fabrication, and general industrial applications. Requirements can be organized by grade, standard, thickness, plate dimensions, surface condition, quantity, and processing requirements.

For a 310-family inquiry, buyers can provide either a short search term or a complete RFQ. The final quotation and supply documents should clearly identify whether the required material is 310 or 310S, especially when the project has specific welding or high-temperature requirements.

Frequently Asked Questions

1. What does “310 SS plate” mean?

It is a common abbreviation for Type 310 stainless steel plate. “SS” means stainless steel. For formal procurement, the exact grade and applicable standard should be stated.

2. What thickness is common for 310 stainless plate?

Heavy-gauge plate is commonly requested in approximately the 3–50 mm range. Actual availability depends on plate dimensions, standard, surface, and supplier inventory.

3. Can I order “310 SS plate” without specifying 310S?

If standard 310 is required, the order should explicitly state 310. Do not assume that a supplier will automatically distinguish 310 from 310S from the abbreviated wording alone.

4. How do I verify that the plate is really 310?

Check the grade and UNS designation on the MTR, then compare the reported chemical composition and product requirements with the purchase specification.

5. What is the best wording for a formal order?

A useful format is ASTM A240 Type 310 stainless steel plate + thickness × width × length + surface + supply condition + quantity. This is much clearer than using “310 SS plate” alone.
