Flame Hardening Stainless Steel

If you can t hold the steel with tongs set it on a larger fireproof work surface.

Flame hardening stainless steel.

The process of flame hardening. Each flame hardening order is assigned a unique operating procedure developed by combining metallurgical study with over 50 years of practical experience. Applied to duplex and precipitation hardening stainless steel grades. Since 1968 penna flame industries has been in the business of flame hardening steel.

It is a surface hardening process in which a thin surface section of a component of hardenable steel is heated rapidly by direct application of high tempe rature flame to a temperature above its upper critical temperature i e it is austenitized and then the component is quickly quenched in water or oil transforming austenite to mar tensite while the. After flame hardening a gray iron casting consists of a hard wear resistant outer layer of martensite and a core of softer gray iron which during treatment does not reach the at transformation temperature. Both unalloyed and alloyed gray irons can be successfully flame hardened. Plus by using robotic flame hardening and our newest advanced robotic induction hardening we can.

Surface hardening of stainless steels grain boundary m 23c 6 boundary of passivity. Flame hardening is the method of surface hardening most commonly to gray iron. Fire is one of the most devastating hazards in the world. Stainless steel stress relieving straightening vacuum processing of all hss and air.

Wear thick gloves so you don t burn yourself. Materials to be treated by low temperature carburising should be in the solution annealed condition. Raise the strength and durability of stainless steel items by tempering them. Consult your machinist s handbook to find the austenitising temperature for your grade of stainless steel.

Although its corrosion resistance somewhat overshadows it the heat and fire resistance of stainless steel is a major property of this metal. The metals are heated to temperatures to their austenization temperature causing the surface to change while the core remains unchanged and soft. Sharp edg es the inside of bores and gaps present no limitation to the process 4 11 12 13. A small flame can erupt into a larger fire or even an explosion.

Use the torch with your dominant hand to heat the entire steel piece before focusing the flame on the area you want hardened such as the end of a screwdriver or chisel. Numerous industries use stainless steel. Induction flame hardening metallurgical facilities and assistance normalize sinter of powder metal spc quality control solution anneal. Penna flame leads the industry in using advanced robotics capabilities to precisely and consistently flame harden or induction harden steel parts to your specifications this process improves wear resistance and increases the longevity of the part.
