Product Description




What type of stainless steel is used in heat exchangers?


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 304 is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel. It is a non-magnetic alloy in the annealed condition, however, becomes magnetic as it is cold worked. It is the most ordinarily utilized of all stainless grades. T304 can be effortlessly welded and is the preferred for many deep drawn, spun or formed parts due to its high ductility.


Stainless Steel Grade 304L has oxidation resistance to a maximum temperature of 1650°F (899°C) continuous without considerable scaling. The maximum temperature for intermittent presentation is 1500°F (816°C). Since 304L is an additional low-carbon variety of 304 it can frequently be utilized in the “as-welded” condition (without annealing), even in severe corrosive conditions, except for applications indicating stress relief. 304L has good welding qualities and can be welded by all standard strategy; however, consideration should be paid to maintain a strategic distance from weld “hot cracking”. To relieve stress during severe forming or spinning welding may be followed by annealing.


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.
