Alloying grades of stainless steel 20X13 chrome 12 — 14%, small additives (up to 1%) of silicon, manganese, Nickel allows to obtain a relatively inexpensive alloy of high corrosion resistance and plasticity, available any kinds of mechanical processing: hot and cold forming, cutting, drilling, polishing, etc. Thanks to the optimal technological and operational parameters such material resists the effects of most of the negative industrial factors, providing reliability and durability of technological equipment. This alloy is used very widely. Analogues: 12H13, 14KH17N2.
