STAINLESS STEEL 446 PLATE

Stainless Steel 446 - 1.4762

This data sheet applies to stainless steel 446 / 1.4762 hot and cold rolled sheet and strip, semi-finished products, bars, rods and sections. Ferritic chrome steels are heat sensitive. Therefore the steel 1.4762 should be welded with the lowest possible heat input by using thin electrode diameter, low current intensity and stringer bead welding. For wall thicknesses under 3mm, it is not necessary to preheat 1.4762. For thicker construction parts (˃ 3mm) the preheating and interpass temperatures 200 - 300°C should not be under respectively over run. 1.4762 can be processed with similar or higher alloyed filler metals. With sulphurous atmospheres a ferritic top layer should be laid on the media side (Thermanit L 1.4820).

Application

For construction parts, which should be resistant to scaling up to about 1150°C and extensively inured to the effects of sulphurous gases. The inclination to carbonisation in reduced gases is very low.
