Description
Изобретение относитс к черной металлургии, в частности к корроэионностойким стал м с высоким сопротивлением абразивному изнашиванию дл форм, предназначенных дл переработки пластмасс.This invention relates to ferrous metallurgy, in particular to corrosion-resistant steel with high resistance to abrasive wear for molds intended for plastics processing.
Известна сталь .1X13 Cl. Наиболее близкой к предлагаемой вл етс коррозионностойка мартенситна сталь 2 95X18, содержаща , вес.%:Known steel .1X13 Cl. Closest to the proposed is corrosion-resistant martensitic steel 2 95X18, containing, wt.%:

Известные стали после закалки и низкого отпуска имеет пониженную твердость (HRC 56-58) из-за значительного количества остаточного аустенита , присутствующего в структуре закаленной стали. Кроме того, они имеют .повышенную адгезию к пластическим массам, что затрудн ет их переработку .Known steel after quenching and low tempering has a lower hardness (HRC 56-58) due to the significant amount of residual austenite present in the structure of hardened steel. In addition, they have increased adhesion to plastics, which makes it difficult to process them.
Цель изобретени - повы ение твердости , износостойкости и устойчивости против адгезии полимеров.The purpose of the invention is to increase the hardness, wear resistance and resistance against adhesion of polymers.
Указанна цель достигаетс тем, что сталь, содержаща углерод, хром, железо, дополнительно содержит титан, ванадий, алюминий, кремний при следующем соотношении компонентов, вес.%: Углерод0,55-0,7This goal is achieved by the fact that steel containing carbon, chromium, iron additionally contains titanium, vanadium, aluminum, silicon in the following ratio of components, wt.%: Carbon 0.55-0.7
