Sheet, tape 40X13 - 1.4034 - aisi 420
Sheet, strip, foil 40X13 martensitic class consists mainly of iron and chromium. In accordance with GOST 5632−72, comprising 12−14% Cr and 0,35−0,44% carbon. The alloy is doped with elements such as Si, Mn, Ni — 0.6%, phosphorus thousandths of shares. Iron is a residue. Smelted in an open electric arc, induction furnaces. Substitute: 30Ch13.
The percentage of the brand 40X13 (GOST 5632−72)
Steel 40X13 heat-resistant, corrosion-resistant. Foil, tape and a piece of this brand are resistant to soil and atmospheric moisture, slightly aggressive media, plastic, differ considerable tensile strength. The tape and the sheet not subject to deformation under load at t ° to 450 ° C, but poorly welded.
The thin sheet is produced in accordance with GOST 5582−75, the band — GOST: 4405−75, 103−76, 968−73 18. Cold plastic deformation is limited. The temperature of hot deformation range of 1100 — 900 ° C. The rapid heating and cooling of the material may crack. Therefore recommended pre-heating the sheet to 850 ° C and gradual cooling in the furnace. In the manufacture of medical instruments recommended hardening speed with cooling in an alkali solution.
