Technical characteristics

Stainless steel grade 18KH12VMBFR (PT 993) is Nickel-free and belongs to the group of high-alloy stainless steels martensite-ferritic class, which differ high corrosion resistance, heat resistance and heat resistance. Due to good ability to plastic deformation of the rolled steel to produce forgings and semi-finished products for further machining and deformation processing of parts such as turbine blades and pipes for pumping the heated working environments. Consider a steel suitable for the production of highly resistant fastening and normalized products. During long-term operation of pipelines, in the heating process up to 640…680°C, the steel does not lose its resilience to creep, corrosion resistance and thermal expansion.
