Cold rolled steel is usually a type of carbon steel which can be broadly Utilized in programs the place precise styles and tolerances are demanded. Cold rolled steels are produced by cold rolling, which consists of passing the steel via rollers in a temperature below its recrystallization temperature.
Even with its medium carbon articles, which typically interprets to bigger hardness, 1141 can also be a lot less severe on machining tools. That makes it something named a “totally free machining steel.” Even so, the additional sulfur implies that 1141 is unsuited to welding.
Community retail outlet prices may well vary from These exhibited. Items proven as offered are normally stocked but stock ranges can not be assured.
