Hardening of structural steel
The company Electrocentury-steel offers to buy the rental case hardening of structural steel in any gauge. Are economically attractive prices from the manufacturer. Provider provides range of products and its prompt delivery to the point specified by the user.
Features of the structure
In the group case hardening structural steel consists of steel with carbon content up to 0.2%.The type is determined by the domestic steel GOST 1050. These steels also contain up to 0.65% of manganese and up to 0.25% of copper, Nickel and chromium. There are also the inevitable metallurgical impurities — sulfur and phosphorus, the percentage of which does not exceed 0,035 0,04…%.
The microstructure of case hardening steels is the combination of high-strength surface layer with a relatively viscous core. This allows us to successfully counteract the recurring stress of bending. However, the relatively low hardness of such steels does not allow to use them in the heavily loaded nodes of mechanisms and machines. Typical representatives of this group of steels are domestic brand steel 20, steel 15KH and the like. Abroad to a group of case hardening steels are steels Ck10, Ck15, CQ15, etc., the smelting of which is made according to DIN 17007.
Properties and applications
Low-carbon structural steel, after heat treatment, carburizing, nitrocarburizing and cyanidation are used:
- In the manufacture of parts such as axles, bushings, small shafts, surface hardness may not be lower than 60…62 HRC;
- With the presence of alloying elements, particularly chromium for the production of piston pins, couplings, guides;
- With the presence of vanadium carburized steel considerably increases their impact strength at alternating loads.
Small additions of titanium to reduce the tendency of cemented steel to overheat. The materials are well handled by pressure in cold and hot conditions.The company Electrocentury-steel offers to buy a variety of rolled case hardening steel at manufacturer’s prices.
