Abstract

Изобретение относится к нержавеющей стали, проявляющей эффект пластичности, наведенной превращением (ПНП), стойкой к замедленному трещинообразованию, и к способу получения нержавеющей стали. Стойкости к замедленному трещинообразованию в нержавеющей стали достигают посредством ограничения общего содержания водорода в нержавеющей стали, которое измеряют методом плавки в инертном газе, до значений менее 4, предпочтительно менее 3 мас.ч./млн, путем термообработки, осуществляемой при температуре от 100 до 700°С в течение 0,1-300 ч, предпочтительно при температуре 200-600° в течение 1-100 ч и более предпочтительно при температуре 250-500°С в течение 1-100 ч.The invention relates to stainless steel, showing the effect of plasticity induced by the transformation (PNP), resistant to delayed cracking, and to a method for producing stainless steel. Resistance to delayed cracking in stainless steel is achieved by limiting the total hydrogen content in stainless steel, which is measured by the method of smelting in an inert gas, to values less than 4, preferably less than 3 parts by weight per million, by heat treatment carried out at a temperature of from 100 to 700 ° C for 0.1-300 h, preferably at a temperature of 200-600 ° for 1-100 h and more preferably at a temperature of 250-500 ° C for 1-100 h.
