Composition

40X13 martensitic grade sheet, strip, foil consists mainly of iron and chromium. According to GOST 5632-72, composition contains 12-14% Cr and 0.35-0.44% carbon. The alloy is alloyed with such elements as Si, Mn, Ni - 0.6% each, thousandths of phosphorus. Iron makes up the rest. It is melted in open electric arc furnaces, induction furnaces. Substitute: 30X13.

Quality

Steel 40X13 is heat-resistant, corrosion-resistant. Foil, tape and sheet of this grade are resistant to soil and atmospheric moisture, mildly aggressive environments, plastic, have a significant tensile strength. Tape and sheet are not subject to deformation under load at t° up to 450 °C, but poorly welded.

Production

Thin sheet is produced as per GOST 5582-75, strip is produced as per GOST: 4405-75, 103-76, 18 968-73. Cold plastic deformation is limited. Temperature range of hot deformation is 1100 - 900 °C. Rapid heating and cooling can cause cracking of material. Therefore, preheating of the sheet to 850 °C and gradual cooling in the furnace is recommended. In the manufacture of medical instruments, step hardening with cooling in an alkali solution is recommended.
