Machining 402 Stainless Steel

The annealing processes involves heating 420 steels over 800°C, and then cooling them in an oven at a lower temperature. Then the steel is removed from the oven and air cooled.

Round 420 Stainless Steel

Steels are preheated at 150 to 320°C and heated at 610 to 760°C during the welding procedure. When pieces are welded in the "as welded" condition, grade 309 filler rods are used to create ductile connections. 420 stainless steel is easier to work with in it’s annealed form.

420 Stainless Steel Sheet

However, grade 420's corrosion resistance characteristics often deteriorate in annealed conditions. Grade 420 steels are resistant to foods, mild acids, fresh water, alkalis, the air, and harsh conditions. 420 steel is used to make cutlery like carving and table knives. Although Grade 420 sheets of steel have considerable resistance to food-related corrosion, prolonged contact with unclean food ingredients can cause pitting corrosion.

Applications of Stainless Steel 420

Grade 420 stainless steel has a variety of applications, often used for cutting things because it is an incredibly hard metal. In the medical sector, it’s used for steel surgical tools like syringe valves. Because 420 steel is dense and corrosion resistant, it is ideal for crucial surgical operations and dental equipment. The steel is wear resistant enough for prolonged contact with human bone. Shear blades are also made of 420 steel because it is easy to sharpen.

420 Stainless Steel

Aside from cutting applications, stainless steel 420 works well for diesel engine pumps used in abrasive non-chlorinated contexts.
