Anti-Dumping Measure on Stainless Steel Tubes

The Commission Implementing Regulation (EU) 2024/1475 of 30 May 2024, imposes a definitive anti-dumping duty on imports of certain seamless pipes and tubes of stainless steel from China, maintaining duties of 48.3% to 71.9%.

Understanding the Mill Finish Stainless Steel Tube Bright Annealing Process

The bright annealing process involves heat treating finished stainless steel products under a protective atmosphere. The metallographic structure required after bright annealing varies depending on performance requirements. For instance, the typical heat treatment process for 300 series austenitic stainless steel involves solution treatment.

Identifying Seamless Stainless Steel Tubes: Four Test Methods

The magnetic test is a straightforward method for distinguishing annealed austenitic stainless steel from ferrous stainless steel. Austenitic stainless steel is non-magnetic but can become slightly magnetic after cold working under high pressure. In contrast, pure chromium steel and low alloy steel are highly magnetic.

Stainless Steel Tube Specifications and Weight Chart

Stainless steel square and rectangular tubes are vital materials widely used for fluid transportation, including oil, natural gas, water, gas, and steam.

Polishing Stainless Steel Tubes: A Comprehensive Guide

Before commencing the polishing process, ensure the stainless steel tube's surface is free from contaminants like dirt, oil, or fingerprints. Clean it thoroughly using a mild detergent and water, then rinse and dry it completely. Identify any pre-existing scratches, pits, or imperfections as they will need special attention during polishing.

Aluminized Zinc Steel Pipe

Aluminized zinc steel pipe involves coating the surface of a steel pipe with a layer of zinc and aluminum to prevent surface corrosion and enhance its longevity. This process, known as galvanization, results in what is commonly referred to as an aluminized zinc steel pipe.
