The company Evek GmbH offers to buy at economical prices from the manufacturer roll-formed tool steels. The supplier guarantees compliance with the grades and assortment of profiles, provides prompt transportation of the ordered products to the consumer.

Peculiarities of the chemical composition of roll tool steels

The optimum choice of steel grade for tool rolls, depending on the rolling temperature. For the rolls of hot strip mills use steel grades 55Kh, 60KhG, 60KhN, and work rolls of cold rolling mills are made of steel grades 9X or 9KhF.

The choice of material is made in accordance with the technical requirements of GOST 9487.

As an example, the chemical composition of steel 60KhG by OST 24.013.21:

The percentage of the main metallurgical impurities - sulfur and phosphorus - must not exceed 0,04%.

Company Evek GmbH offers to buy for a price from the manufacturer roll tool steel in a wide range of grades and assortment. The supplier guarantees timely delivery of products to the address set by the customer.

Properties and application features

All roll tool steels are sensitive to flaking, so the recommended temperature deformation intervals should be strictly observed during hot plastic deformation. The steels are also satisfactorily workable in the cold state, but the metal-cutting tools must be made of high-speed steel or hard alloys.

Physical and mechanical characteristics of roll tool steels:

• Tensile strength, MPa - 800...910 (lower values - for hot-rolling tools);
• yield strength, MPa - 520...580 (lower values - for the hot-rolling tool);
• Elongation factor, % - 18;
• Coefficient of relative contraction, % - 45...50;
• Impact toughness, ^kJ/m2 - 350...360.

Evek GmbH offers to buy for favorable price from the manufacturer roll tool steel of various grades and assortment. Deliveries are made promptly, with delivery of purchased products directly to the customer.
