Grade 430 resists oxidation in intermittent service up to 870°C and to 815°C in continuous service. This grade may become brittle at room temperature after prolonged heating in the 400-600°C range. This effect can be eliminated by annealing.

The Brinell hardness will scale the hardness of materials by the penetration depth of an indenter, which means we need to punch a small pit on the surface of the metal castings. The Rockwell hardness determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.
There are a large number of hardness testing methods available ( Vickers, Brinell, Rockwell, Meyer and Leeb).Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.. Hardness comparison tableSome results are removed in response to a notice of local law requirement. For more information, please see here.

May 04, 2016 · For most of my knives, the hardness is between 58 and 62 RC, and that works well for a good mix of toughness and edge-holding with steels ranging from tried and true like 1095 and 5160 to expensive and high tech like VG-10 and INFI.
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.
Oct 26, 2001 · Welding. To perform any welding, stainless steel grade 430 has to be pre-heated at 150-200°C (302-392°F). In case of embrittlement in the welded metal, the particular area can be post-weld annealed at 790-815°C (1454-1499°F); however grain refinement will not happen.

Stainless steel hardness is one of the most important characteristics when choosing the material for a specific application. Of course, stainless steels are well known for their resistance to corrosion, but these steel can also be considerably strong depending on how they are produced.
