Materials
Common Trade Name
304 High Carbon
Material Grade
304H
UNS
S30403
Specification
ASTM A479
Approx. Room Temp. Mechanicals
"T = 75 ksi, Y = 30 ksi"
Typical % Composition Summary
"Cr 18, Ni 8.0 - 10.5, C .04 - .10"
Applications
"Used primarily when material is subjected to extreme temperatures. The high carbon helps retain strength at the elevated temperatures."
Corrosion Resistance
"Austenitic Cr - Ni stainless. Better corrosion resistance than 302. Essentially non-magnetic, becomes slightly magnetic when cold worked. Lower carbon content means less carbide precipitation in the heat-effected zone during welding and a lower susceptibility to intergranular corrosion."
