STAINLESS STEEL SEAMLESS PIPE
Austenitic stainless steels such as Type 304 and Type 316 are frequently selected for heat exchangers placed in cooling water service. These alloys generally perform well in clean water and are expected to give a long service life withminimal problems
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.
