202 hot rolled stainless steel seamless pipesolution. Water quenching after heat the steel to 1050-1150 ° c, the main objective is to make the carbides dissolve in austenitic, and this status is reserved to room temperature, which will greatly improve corrosion resistance steel. As noted above, in order to prevent corrosion of Crystal asked, usually in solid solution treatment, Cr23C6 dissolves in austenite and then quickly cooled. For thin - walled parts can be air cooled, generally using water cooling.
