URSSA 16Mo3/13CrMo4-5. Steel for high work temperatures
Resistant to temperatures from 300 ° C to 600 ° C in chemical, petrochemical and cement steels.
Soldering: Excellent
Folded: Excellent
Transformation: Excellent
Mechanization: Excellent
Typical applications
Mo and Cr-Mo alloyed steels.
Its warm resistance properties, have a large range application in the chemical industry, petro chemistry, cement producer, etc., when are needed work temperatures between 350ºC and 600ºC. Molybdenum improves the mechanical characteristics in high temperatures while Cromo increases specially the resistance, long-lasting steel’s life.
Building elements that have to support temperatures over 300ºC during long service time, should be build with this type of steels resistances to the creep.
