GOST 5950−2000
The standard applies to hot-rolled, forged, calibrated bars and strips, steel with special surface finish of low-alloy, medium-alloy and high-alloy tool steel. In terms of chemical composition this standard applies to steel grades ZKh2MNF, 4KhMNFS, 9KhFM, as well as ingots, blooms, slabs, billets, forgings, sheet, strip, pipes and other steel products. Evek GmbH offers to buy a wide range of alloy structural steel at an affordable price. Provide delivery of products anywhere in the continent. The price is optimal.
Classification. By the purpose of metal products
1. Manufacture of tools used mainly for processing metals and other materials in a cold state;
2. manufacture of tools used mainly for metal forming with pressure at the temperature over 300 °C.
According to the method of processing
a — for hot deformation by pressure;
b — for cold machining (turning, gouging, milling, etc.).
According to the state of the surface
O — standard quality, P — improved quality.
Alloying
Low-alloy tool — 8KhF, 9KhF, 9KhFM, 11KhF, 13Kh, V
medium alloyed instrumental — HV
High-alloy tool — Kh12, Kh12VMF, Kh12MF, Kh12F1, 05Kh12N6D2MFSGT.
Molybdenum
The minimum mass fraction of molybdenum in 5CrNiM composition shall be 0.10%. The sum of molybdenum and tungsten in terms of molybdenum must not be less than 0.15% or more than 0.30%. The minimum mass fraction of molybdenum in the composition of 5X2MNF shall be 0.40%. The sum of molybdenum and tungsten in terms of molybdenum must not be less than 0.80% and more than 1.20%. With a mass fraction of tungsten over 0.20% steel alloy is marked 5X2VMNF.
On Demand
By customer request, steel alloy grades 8XF, 9XF, V
GOST 19265−73
This standard applies to hot-rolled, forged, calibrated bars and strips, bars with special surface finish (hereinafter — metal products), in terms of chemical composition norms — for sheet, strip, forgings, forgings and other types of metal products from high-speed steel. which are manufactured in the form of bars and strips. In terms of shape, dimensions and limiting deviations, rolled steel must meet the following requirements:
GOST | Steel |
2590−88 и 2591−88; | hot-rolled round and square sections |
1133−71 | Forged |
4405−75 | strip |
7417−75 | calibrated |
14955−77 | steel with special surface finish in diameter from 1 to 25 mm |
Metal products are subdivided by macrostructure and carbide heterogeneity into groups: Group I (diameter or thickness from 80 to 200 mm), Group II (diameter or thickness up to 150 mm). According to the method of further processing into subgroups:
for hot work with pressure,
For cold machining.
Hardness of high-speed steel in annealed state, hardness of samples after quenching and tempering, temperature of quenching and tempering should correspond to the values given in the table:
Steel grade | Steel hardness | Temperature, °С | |||
after annealing | after quenching with tempering HRC not less | tempering | tempering | ||
NV, no more | imprint diameter, mm, no less | ||||
