Compare common steel designations across ASTM, AISI, SAE, EN, DIN and JIS systems and find possible comparable grades.
Enter a steel grade and click Find Cross References.
Always check the exact material standard, product form, heat-treatment condition, chemical limits, tensile strength, yield strength, hardness, impact requirements and certification requirements before specifying a substitute.
What is a steel grade cross-reference tool? It maps selected steel designations between different standards and identifies grades that may be comparable.
Are cross-referenced grades identical? No. Comparable does not necessarily mean identical. Standards can differ in chemistry, mechanical properties, testing and delivery condition.
What is the difference between ASTM and AISI designations? They are different designation and specification systems. AISI/SAE designations are commonly used for alloy and carbon steel chemistry, while ASTM specifications often define material requirements for particular products and applications.
Can I replace an EN grade with an ASTM grade? Only after checking the relevant specifications and engineering requirements. A simple name match is not sufficient for critical applications.
Does the tool cover stainless steel? Yes. Selected common stainless grades such as 304, 316, 321, 410 and 430 are included.
Does the tool cover structural steel? Yes. Selected structural grades are included, including S235 and S355 families.
Does the tool include JIS grades? Yes. Selected JIS grades are included for comparison with other systems.
Why can one grade have several possible equivalents? Different standards can use different designation systems and specifications, and several grades can have similar chemistry or intended applications.
Can this tool be used for purchasing steel? It can help with preliminary comparison, but the purchasing specification should identify the exact standard, grade, product form and required condition.
Can this tool certify material equivalence? No. Final equivalence must be established from the applicable standards and technical requirements.
