Sheet, strip 3Х2В8Ф - X30WCrV9-3 - 1.2581

Sheet, strip 3Х2В8Ф - X30WCrV9-3 - 1.2581

Technical specifications

Steel tool alloy. The temperature of the critical points is Ac 1 = 800, Ac 3 (Acm) = 850, Ar 3 (Arcm) = 750, Ar 1 = 690, Mn = 380. Hardness after heat treatment (GOST 5950−2000) HB 10 -1 = 229 MPa. This steel is not used for welded structures. Prone to temper brittleness, sensitive to the formation of flokens. The supplier Avlob offers to buy a sheet, a strip of mark 3Х2В8Ф, 1.2581 at an affordable price today. The best price from the supplier.

Heat treatment

Tempering 1130 ° C, oil, tempering 650 ° C, 2 hours

Mechanical properties (temperature 20 ° C)

  1. sв — Short-term strength limit: 1530 MPa
  2. sT — Proportionality limit (yield stress for permanent deformation): 1390 MPa d5 — Elongation at break: 12%
  3. y — Relative narrowing: 36%
  4. KCU — Impact strength: 200 kJ / m 2

Using

A heavily loaded press tool (dies and punches for extrusion, etc.) with hot deformation of alloyed structural steels and high-temperature alloys, die-casting molds of copper alloys.
