Chemical composition
Steel brand 38KHS refers to a group of steels that are additionally alloyed with silicon and chromium. Steel is smelted domestic metallurgical industry, respectively the technical requirements of GOST 4543. The composition of steel is presented in the table:
Item | Carbon | Silicon | Manganese | Chrome | Copper | Nickel |
---|---|---|---|---|---|---|
The percentage of steel | 0,34 0,42… | 1,0…1,4 | 0,30…0,60 | Of 1.30…1.60 | Not above 0,30 | Not above 0,30 |
The standard allows the presence of steel 38KHS traces of molybdenum (up to 0.15%). The percentage of metallurgical impurities in the composition of the steel of sulfur and phosphorus shall not exceed 0,035%.
The closest analogue of steel 38KHS in Europe is the steel 37hs. It is made of Polish iron and steel companies, and must comply with the requirements of the national Polish standard PN-H-84030. This steel differs from 38KHS lack of molybdenum in its composition.
Buy at factory price bulk Bicycle tube, rod, round, which are made of alloy of chromium and silicon structural medium-carbon steel grades 38KHS and 37hs, the company offers Electrocentury-steel. The supplier guarantees the timely delivery of our products to a point noted by the consumer.
Properties and applications
Forgings of steel grades 38KHS and 37hs used for the production of mechanical parts of transmission shafts, shafts, gears, small gears and other products of similar purpose, for durability where you need the optimum combination of high contact strength with a viscous core. Steel prone to embrittlement after the holidays, and has a reduced ability to weld (after welding requires a hardening heat treatment).
The mechanical characteristics of the considered steels after quenching and tempering are:
- Limit strength — 730…900 MPa;
- Yield strength — 590…650 MPa;
- Elongation — 12…15%;
- The relative narrowing of 50…52%;
- Brinell hardness number — not higher than 230 HB;
- Impact strength — 600…700 kJ/m2 .
To buy at economical price from manufacturer of pipe, round, rod, made from alloy structural steel grades 38KHS and 37hs the company offers Electrocentury-steel. The supplier shall ensure the strict observance of the range of the products which ensures its timely delivery to the point specified by the customer.
