What is ASTM-A269?

Everyone is often familiar with GB/14976, GB13296, and the American ASTM-A312 and A123 standards. In fact, there are many stainless steel pipe standards, but the more popular ones are the above-mentioned national standards GB and ASTM standards. When some customers require the standard of 304 stainless steel pipe to be ASTM-A269, can the products we produce meet this requirement? How to quote the price? Today let's analyze the differences between A269 and other standards.

The American standard corresponding to the GB/14976 standard is ASTM-A312; the corresponding American standard to GB13296 is ASTM-A213; the A269 standard is written as ASTM-A269 is a general standard specification for seamless and welded austenitic stainless steel pipes. In fact, the requirements of this standard are relative to It's relatively high. Cold worked austenitic stainless steel welded pipes and seamless pipes for cold working are ASTM-A312.

At present, the most commonly used type of ASTM-A269 stainless steel pipe is BA grade bright annealed pipe. Its precision can reach ±0.05mm, and its internal and external surfaces are extremely clean. For example, most customers of the BA grade stainless steel pipes produced by Huadun are used in gas pipelines, medical and other fields, and the price is relatively high.
