Stainless Steel 420

SAM_2180 (Small)
Description Thermal Spray coatings of Stainless Steel 420 are used in applications which require hard surfaces with good wear and corrosion resistance. The low shrinkage properties of Stainless Steel 420 allow it to be applied up to several millimeters thick on curved surfaces, such as shaft journals and internal diameters. During the coating process the maximum component temperature is monitored and controlled to remain below 70˚C in order to prevent any distortion. The low coating app...
