Production technology stainless steel square
Stainless square is produced from structural corrosion-resistant steel. Use of such steel grades as: 10H17N13M3T, 10H17N13M2T, 17H18N9, 12H13, 12KH18N9T, 12H18N9, 12H18N10T, 20X13, etc. In the numerical-letter acronym reflected the main components. For example, 12X18H10T. 10 means to 0.10% carbon ©, X18 — about 18% Cr. H10 means 10% Ni, T is about 1% Ti. The share of Nickel and chromium determines the corrosion resistance.
Percentage composition according to GOST 5632−72
If chromium more than 17% in the aggressive oxidizing environment, the material will have different special corrosion resistance. Nickel in addition to anti-corrosion properties, said alloy impact resistance and ductility. Titan gives the square of the heat resistance and improve the wear resistance of the semi-finished product.
The disc is heated to a temperature of 1250 °C, then served on the blooming. If necessary, the blank is cut, At the blooming mill hot billet for square undergoes primary treatment. Horizontal and vertical rolls it alternately compresses. In one approach, the mill compresses the product to 12 cm To achieve the necessary parameters required 15 — 20 passes. After finishing rolling is carried out the calibration. It can be high, high, normal accuracy, accordingly it is marked by the letters A, B, C, Standard stainless square has a cross section of 20 cm in the case that the cross section of the product, more it is produced, indicating the special order.
