What is CB6 Stainless Steel ?
CB6 alloy is a martensitic steel alloy used for casting. It is usually provided under heat treatment conditions. This steel incorporates high quality, low weight, high solidness, high ductility, and protection from erosion.
CB6 stainless steel has medium-high ductility in cast martensitic stainless steel. In addition, it has a moderately high PREN and a moderately high intrinsic energy. It has medium-low conductivity in cast martensitic stainless steel.
Also, it has medium-low thermal conductivity and high ductility.CB-6 stainless steel is usually used in casting, sample testing, plate transportation and support, shipping, aviation, etc.
