DIN 17457 is a German Industrial Standard (German Institute for Standardization) that specifies the requirements for austenitic stainless steel welded pipe. These pipes are primarily used in corrosion-resistant applications, particularly those requiring hygienic, high-purity, or chemical resistance.
What is the equivalent material for DIN 17457 stainless steel welded pipe?
DIN 17457 stainless steel welded pipe is equivalent to ISO, ASTM, and EN standards (for example, EN 10217-7 for stainless steel welded pipe). It is similar to ASTM A312 (seamless/welded austenitic pipe) or DIN 11866 (for pharmaceutical tubing).
Typically made from austenitic stainless steels such as:
1.4301 (equivalent to AISI 304)
1.4401/1.4404 (equivalent to AISI 316/316L)
1.4541 (equivalent to AISI 321)
Depending on the specific application, this standard may cover other austenitic steel grades.
Manufacturing Process
Welding (typically TIG or laser welding) is employed, followed by cold working (cold drawing or cold rolling) to improve mechanical properties. Some grades may be annealed (heat treated) to enhance corrosion resistance and ductility.
