Description
Austenitic Mn-steel. The well-known Hadfield steel still has broad applications in the mineral processing industry. Especially under impact loading Hadfield steel displays good wear resistance due to its high cold work ability. However, Hadfield steel is not corrosion resistant.
Applications
Components for dredgers and crushers, conveying machines: crushings jaws, impact wedges, linings, etc.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 190-210
Density [g/cm3]: 7.88
Hardening
Harden from a temperature of 1000-1050oC followed by water quenching. Hardness after quenching is about 200 HB.
Mechnical properties at ambient temperature:
0.2 % proof stress (N/mm2): 350
Tensile strength (N/mm2): 800-1000
Forging
Hot forming temperature: 1050-850oC
Machinability
The machinability of this steel is poor.
Forms manufactured: Please see the Dimensional Sales Program.

304 is a versatile stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability).
301 stainless steel exhibits obvious work hardening phenomenon during deformation, and is used in various occasions requiring higher strength.
302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content, which can be obtained by cold rolling to obtain higher strength.
302B is a stainless steel with high silicon content, which has high resistance to high temperature oxidation.
304L is a variant of 304 stainless steel with a low carbon content and is used in applications where welding is required. The low carbon content minimizes the precipitation of carbides in the heat-affected zone close to the weld, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in certain environments.
304N is a kind of stainless steel containing nitrogen. Nitrogen is added to improve the strength of the steel.
305 and 384 stainless steels contain high nickel, and their work hardening rate is low, which is suitable for various occasions that require high cold formability.
308 stainless steel is used to make welding rods.
The 309, 310, 314 and 330 stainless steels have relatively high nickel and chromium content in order to improve the oxidation resistance and creep strength of the steel at high temperatures. The 30S5 and 310S are variants of 309 and 310 stainless steel, the difference is that the carbon content is low, in order to minimize the precipitation of carbides near the weld. 330 stainless steel has a particularly high carburization resistance and thermal shock resistance.
Type 316 and 317 stainless steels contain molybdenum, so their resistance to pitting corrosion in marine and chemical industrial environments is much better than that of 304 stainless steel. Among them, 316 stainless steel variants include low-carbon stainless steel 316L, nitrogen-containing high-strength stainless steel.
316N and free-cutting stainless steel 316F with high sulfur content.
321, 347 and 348 are stainless steels stabilized with titanium, niobium plus tantalum, and niobium, respectively, and are suitable for welding components used at high temperatures. 348 is a stainless steel suitable for the nuclear power industry, which has certain restrictions on the amount of tantalum and drill.
304L stainless steel has poor forging performance and is difficult to deform. Due to work hardening. So that the amount of deformation in the process of pulling the core rod can not be given too much. And the heat loss is large. Therefore, it must be shaped under the teaching of more fires. If it is not handled well at high temperature, it will cause coarse crystals.
