Composition and properties
Flat steel medium-alloyed structural steel 50KHFA produced in a wide range of thicknesses and lengths. The chemical composition of the steel of domestic production determines GOST 14959. Chemical composition of steel, the following:
|The percentage||0,45…0,55||0,17…0,37||0,50…0,80||0,80 1,10…||To 0.40||0,10…0,20|
As a metallurgical impurities in the composition of the steel, the sulfur being present (not more than 0,025%) and phosphorus (not more than 0,020%).
In Poland is similar to the characteristics of steel 50hf and in Germany analog steel 50 HPA according to DIN 50CrV4 steel is considered. The composition of these steels, in contrast, from 50KHFA, has enhanced tolerances on the content of carbon, manganese, and Vice versa — a lower silicon content.
Physico-mechanical parameters of the steel grade:
- Tensile strength tensile, MPa — 940;
- The plastic limit, MPa — 820;
- The relative elongation, % — 20…22 (a lower value corresponds to the rental sheet);
- Impact strength at temperatures of up to 150…2000 C, kJ/m2 — 37.
- Brinell hardness number, HB — 265…310.
All the considered steel grades are successfully exposed to various types of heat treatment — annealing, tempering, vacation. Steel type 50KHFA are delivered to the consumer in a wide range of thickness, length and width of the rolled sheet, and strip.
Steel 50KHFA (and its listed analogues) used in the manufacture of springs responsible, the terms of which require increased durability of products. Steel are resistant to elevated temperatures (up to 3000 C) and changing the sign operational loads. Ability to weld low-shoeing, you must perform with small relative deformations.
To buy rolled metal strip, sheet, tape — steel spring classes from the company Electrocentury-steel economically. In the sale are the prices of the products manufacturer, and all of the acquired lot is accompanied with certificate of quality.
