With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened.
Heat Treatment. Stainless steel grade 420J2 has to be heated uniformly to 730-790C (1346-1454F) and held until temperature is uniform throughout the section. Hardening. Stainless steel grade 420J2 can be hardened by heating 950-1020C (1742-1868F) and held until temperature is uniform throughout the section.
The 420j2 stainless steel is a popular choice for knife manufacturers. 420j2 stainless steel contains medium quality carbon content. It has good corrosion resistance in salt-free atmospheres and in most industrial environments. It is resistant to many chemicals and household cleaners; and, it is also a more durable steel compared to the 440 grades.
316 1.4401 316L 1.4404 Heat Treatment. Annealing The austenitic stainless steel are provided in the mill annealed condition ready for use. Heat treatment may be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated chromium carbides resulting from thermal exposures.
Some frame locks have 420J2 listed as the used frame material(for example on my buck/mayo hilo), but many other that are made of for example 410-steel only write stainless steel liners/frame on their site, without being specific. So is 420J2 really stronger than other 410/420 steels, or has it got other significant advantages?
Not a problem with shop air at all. Also, you never know if the blade, or edge could have become warped during heat-treat. Leaving the blade in the wrap, and plate quenching, prevents you from being able to check for this while the blade is still in a heat range where it can be safely straightened, with out the possibility of cracking.

Cold-rolled stainless steel plate due to the good hardening, toughness is low. In order to ensure all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties to meet the requirements, prior to delivery must be stainless steel annealing, solution treatment, aging heat treatment.

A. 410 is a funny stainless steel. Depending on the carbon content, you MIGHT be able to harden it per AMS2759/5 [link by ed. to spec at TechStreet], the standard aerospace heat treat specification, to Rockwell C 40 or more. We find we have to specify the hardening capability of the 410 we buy when we purchase it.

Heat Treatment in 410 Stainless Steel We have a castings Impellers in 410, your thickness is 19 mm and the hardness is 45/50 HRC. We made the heat treatment at 980 C and cooling in oil at 60 C and the harness was 30 HRC Retreatment at 980 C and cooling in strong air at 60 C - strees relifing at 320 C and the hardness was the same.
HEAT TREATMENT OF STAINLESS STEELS S. Chaudhuri National Metallurgical Laboratory Jamshedpur 831007 1.0 INTRODUCTION Over a few decades various means of retarding or preventing corrosion of iron and steel products have been extensively used. These include painting or coating with metals or sometimes nonmetals that proved
420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties.
