ASTM certification requires suppliers to pass spectral analysis, tensile testing, hardness testing and other testing methods, and follow quality management systems such as ISO 9001.

ASTM A240 certified stainless steel plates are core materials in the fields of pressure vessels, building structures and high-end equipment. This standard, developed by the American Society for Testing and Materials, regulates the chemical composition, mechanical properties and production process of stainless steel plates to ensure their reliability in extreme environments.

ASTM A240/A240M is applicable to chromium, chromium-nickel and chromium-manganese-nickel stainless steel plates, sheets and strips, covering four major categories: austenite, ferrite, martensite and duplex stainless steel. Its core categories include:

200 series (such as 201, 202): low-cost high-manganese steel, suitable for non-harsh environments.

300 series (such as 304, 316, 430): high corrosion resistance, leading the food, chemical and construction industries.

Chemical equipment: reactors, heat exchangers and piping systems (compliant with ASME pressure vessel specifications).

Food and medicine: storage tanks, delivery pipelines (316L is more suitable for high chloride ion environments).

Building curtain walls: 304/316 stainless steel is used for exterior walls and roof structures in coastal high salt fog areas.

We have set up a professional and standardized product testing center laboratory, and strictly control product quality by building a scientific and complete testing system. The various testing items and professional instruments equipped in the laboratory strictly follow international standards, and use advanced technical means and strict testing processes to fully guarantee the reliability and stability of product quality, and provide customers with trustworthy high-quality products.
