Roller tool steel
To buy at economical price from the manufacturer to rent the roller tool steel, the company offers Electrocentury-steel. The supplier guarantees the compliance of brands and assortment of profiles, ensures prompt transportation of the ordered products to the consumer.
The chemical composition of a roller of tool steel
The optimum selection of the steel grade for the rolls depends on the temperature of rolling. Roll garageparty mills use steel grades 55KH, 60ХГ, 60ХН and work rolls of cold rolling mills made from steel grades 9X or 9KHF.
The choice of material is made in accordance with the technical requirements of GOST 9487.
In the example of the chemical composition of steel 60ХГ for OST 24.013.21:
|The percentage||0,55…0,65||0,17…0,37||0,80 1,00…||…Of 1.00 to 1.30||To 0.40|
The percentage of major metallurgical impurities — sulfur and phosphorus should not exceed 0,04%.
The company Electrocentury-steel offers to buy at price from manufacturer, roller tool steel in a wide range of brands and assortment. Supplier guaranteed timely delivery of products to the address set by the customer.
Properties and application features
All roller tool steel is sensitive to flokirovanie, so when the hot plastic deformation is necessary to strictly observe the recommended temperature intervals of deformation. Steel are also satisfactory workability in a cold state, however, the cutting tool must be made of high speed steel or hard alloy.
Physico-mechanical characteristics of rolling of tool steel:
- Tensile strength, MPa — 800…910 (smaller values for tool hot-rolling);
- Yield stress, MPa 520… 580 (smaller values for tool hot-rolling);
- The coefficient of elongation, % — 18;
- The coefficient of relative narrowing, % — 45…50;
- Impact strength, kJ/m2 — 350…360.
Buy at best price from manufacturer, roller tool steel of various grades and range offered by the company Electrocentury-steel. Delivery is performed promptly, with delivery of the purchased products directly to the consumer.
