M4 Tool Steel Tensile Strength

Us bolts tensile strength and proof loads.

M4 tool steel tensile strength. However the high hardness and high vanadium carbide content make it more difficult to grind after heat treatment compared to m2 and other high speed steels. T11304 is the uns number. Stainless steel special steel compressor blading turbine blading superalloy supplier. This page shows summary ranges across both of them.

These rods are decarb free for a uniform surface that will consistently accept heat treating. The best blade steels exhibit a balance of strength and toughness. A large volume of vanadium carbides provides the high wear resistance. Blade steels with an insane amount of hardness pushing towards 70 hrc tend to lack stability and can suffer from cracks chipping and total failure.

Tool die steels inc. Tensile yield strengths and ductilities for some of the plain carbon and low alloy steels are given in the following mechanical properties of steel chart. Made from powdered metal m4 tool steel has a consistent microstructure that gives it outstanding resistance to wear and abrasion. M4 is the designation in both the sae and aisi systems for this material.

For instance m4 high speed steel s chemical content is nearly identical to m2 high speed steel except m4 contains 4 vanadium instead of 2. Some notes from iso 898 metric screw threads standards. The properties of sae aisi m4 steel include two common variations. Astm m4 round bar astm m4 flat bar astm m4 hollow bar astm m4 tube pipe astm m4 sheet plate astm m4 strip coil astm m4 wire astm m4 forging astm m4 tube pipe tel 86 13880247006.

M4 steel may outperform blade steels such as m390 and s90v in terms of edge retention and m4 is in. Hs 6 5 4 e m4 skh 54 stark. Sae aisi m4 steel is a tool steel. D for structural bolting.

Griggs steel color code. For more specific values follow the links immediately below. The high carbon content enables m4 steel to be hardened in excess of 65hrc. 70000 n m12 95500 n m14 and 130000 n m16 mass and weight the difference.

Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. Despite the high levels of molybdenum and tungsten carbides about 6 tungsten 5 molybdenum in each grade the small difference in vanadium content gives m4 nearly twice the wear life of m2 in many. Cpm rex m4 hc powder metal high speed steel. It is comparable to cpm rex m4.

Yield strength tensile strength and ductility values for steels at room temperature. Use it for punches dies and high speed cutting tools.
