What is an ASTM steel specification? An ASTM specification establishes requirements for a defined steel product or material category. Requirements can include chemical composition, mechanical properties, dimensions, testing and manufacturing conditions.
What is ASTM A36? ASTM A36 is a widely used carbon structural steel specification for structural shapes, plates, bars and related products.
What is ASTM A106 Grade B? A106 Grade B is a seamless carbon steel pipe grade commonly specified for elevated-temperature service.
What is ASTM A516 Grade 70? A516 Grade 70 is a pressure-vessel steel plate grade commonly selected for welded pressure-vessel applications requiring good notch toughness.
What is ASTM A335 P22? P22 is an alloy steel pipe grade under ASTM A335, commonly associated with chromium-molybdenum high-temperature service.
What is ASTM A312 TP316L? TP316L is a low-carbon austenitic stainless steel pipe grade with molybdenum for improved corrosion resistance.
Is ASTM A240 316 the same as ASTM A312 TP316? They can refer to the same basic stainless alloy family, but the specifications cover different product forms and impose their own requirements. The complete specification should always be checked.
Does an ASTM specification identify one exact chemical composition? Not necessarily. Many ASTM specifications contain several grades, and permissible composition ranges depend on the specific grade and product specification.
Can I use an ASTM grade as an automatic equivalent to another standard? No. Cross-reference should be verified carefully because equivalent-looking grades may have different chemistry, mechanical requirements, product forms or certification requirements.
Does this tool replace the ASTM standard? No. It is a quick reference. The current applicable ASTM specification and material certificate should be used for engineering, procurement and safety-critical decisions.
