420 Stainless Steel
.054" x 12" x 21"
Type 420 Stainless Steel, a modification of 410, has a higher carbon content to increase hardness, improve strength and give better wear resistance. This type maintains its best corrosion resistance in the heat treated condition. Tempering temperatures above 700° F. are not normally recommended and Type 420 must be preheated before and annealed after welding.
