With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
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.
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.
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.
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.

How to reach HRC38 for SS410. A discussion started in 2008 but continuing through 2017. May 26, 2008. Q. Dear Sirs, I am a supplier quality engineer. I have one component the surface hardness should be over HRC38 and the raw material is SS410. Through the normal quenching & temper process, the hardness cannot meet our requirement (only HRC35-37).
304 Heat Treatment According to ASTM A213 ,the austenitic stainless steel are heat treated to remove the effects of cold forming or to dissolve precipitated chromium carbides. The surest heat treatment to accomplish both requirements is the solution anneal which is conducted in the 1850F to 2050F range (1010C to 1121C).
Beginning with heat treatment and sub-Critical Annealing: Heat treatment begins by uniformly heating the steel to 730 C 790 C and keep the temperature there until the temperature is the same throughout the piece of steel. The next step is soaking the steel and air cooling it.
AISI/SS 420 / 420J1 / 420J2 Plate is manufactured from high-grade carbon steel with 13% chromium content. These SS grade plates are hardened by the heat treatment process. The material grade is magnetic and heats treated by the tempering and quenching proces

Heat Treatment. Thanks to the addition of Carbon in its structure, Stainless Steel 422 can be hardened and strengthened by standard heat treatments used for carbon steels such as hardening, annealing, and tempering. Depending on the wanted qualities, different combinations of these heat treatments are recommended.
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 is a general purpose medium carbon straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance. It is generally supplied hardened and tempered either in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255, or in the tensile range 770 - 930 Mpa (condition S)

: Every time we find it difficult to take gaurd and do impact testing and accept based on impact results.: The SS 420 material are checked by us for chemical properties and only those conform to standard requiremtns are taken for machining and heat treatment.: Any way this problem can be solved.
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.
condition the steel is just machinable. Following machining, forming etc. the steel can be hardened by a single, fairly low temperature "ageing" heat treatment which causes no distortion of the component. CORROSION Although the main reasons why stainless steels are used is corrosion resistance, they do in fact
Stainless Steel grade AISI 420 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
Hi Ali Generally you do not need to perform any post weld heat treatment, (PWHT) because the Nb added to the base metal and filler will tend to stabilize the weld and HAZ. As with all Austenitic alloys, you just need to weld it relatively cold, with a relatively low heat input.
