GOST of powders of precision alloys
Are you interested in GOST for powders of precision alloys from the supplier company AvecGlob? Here you will find interesting information on this topic.
General Provisions
GOST 13084−88 applies to powders of high-alloy steels and alloys made by the method of joint reduction of mixtures of oxides with metal powders by calcium hydride. Powders are intended for the manufacture of corrosion-resistant products, machine parts, instruments, porous and dense sheets, tapes, wires, metallurgical semi-finished products (forgings, bars, ribbons, pipes) and for other purposes.
Technical requirements for powders include a set of provisions on the chemical composition of powders and the technological regulations for its production.
Powders of high-alloy steels and alloys are divided:
- by chemical composition — on the brands ПХ17Н2, ПХ18Н15, ПХ23Н18, ПХ18Н9Т, ПХ30, ПХ20Н80, ПХ13М2, ПХН28МДТ, ПХ40Н60;
- by granulometric composition;
- on the maximum grain size: large — 280 microns, medium — 160 microns, small — 56 microns;
- by bulk density — on 21, 23, 24, 25, 26.
The symbol for the powder is indicated with the following abbreviations:
powder — P;
powder grade — the letter designation of the element and the number indicating the average content of the element in percent;
granulometric composition — 280, 160, 56;
bulk density — 21, 23, 24, 25, 26.
