Grade 304L SMLS Stainless Steel Seamless Pipe
304(1.4301)/304L(1.4307)/304H(1.4948) SEAMLESS&WELDED PIPE
Stainless Steel Grade 304H includes a high carbon content making the steel more suitable for utilization in applications where high temperatures are available. The benefit of this grade is that it is an austenitic chromium-nickel steel alloy as well as the greater carbon content distribute to increased tensile and yield strength. The material is recommended for utilizing in ASME pressure vessels in working service above 525° C because of the grade's heat resistant properties.
