Description
В насто щее врем дл изготовлени различных деталей в различных установках известно применение низколегированных сталей перлитного класса.At present, the use of low-alloyed pearlite steels is known for the manufacture of various parts in various installations.
Особенность описываемой стали заключаетс в том что, с целью повышени ее релаксационной стойкости, она в своем составе имеет углерод , марганец, кремний, хром, никель, молибден , ванадий, серу и фосфор в определенных количествах, установленных экспериментальным путем . Описываема сталь предназначаетс дл изготовлени деталей крепежа и шпинделей арматуры энергетических установок с паралгетрами пара 140 атм и 570° имеет следующий химический состав: углерода 0,18-0,25%, марганца 0,25-0,50%, кремни 0,15-0,35%,хрома 1,0- 1,3%, молибдена 0,8-1,2%, никел - менее 0,6%, ванади - в размере учетверенного процента содержани углерода (v 4C%), серы - менее 0,03% и фосфора -менее 0,03%.The peculiarity of the described steel is that, in order to increase its relaxation resistance, it contains carbon, manganese, silicon, chromium, nickel, molybdenum, vanadium, sulfur and phosphorus in certain quantities established experimentally. The described steel is intended for the manufacture of fasteners and spindles of fittings of power plants with steam parameters of 140 atm and 570 ° and has the following chemical composition: carbon 0.18-0.25%, manganese 0.25-0.50%, silicon 0.15- 0.35%, chromium 1.0-1.3%, molybdenum 0.8-1.2%, nickel - less than 0.6%, vanadium - in the amount of four times the percentage of carbon content (v 4C%), sulfur - less 0.03% and phosphorus less than 0.03%.
После термической обработки (закалка - при 1000 и отпуск - при 700° в течение 4 час.) описываема сталь имеет следующие механические свойства:After heat treatment (quenching at 1000 and tempering at 700 ° for 4 hours), the steel described has the following mechanical properties:
