WHY IS STAINLESS STEEL ALSO MAGNETIC? 316 stainless steel belongs to austenitic stainless steel. Austenite is partially or a small amount transformed into martensite during cold working. Martensite is magnetic, so 316 stainless steel is non-magnetic or slightly magnetic. That is to say, It is not possible to determine whether it is stainless steel by judging whether it is with magnetic or not! WHY CHOOSE OUR HEX HEAD CAP BOLTS? Use 316 stainless steel with moisture resistance, corrosion resistance and high tensile strength Compared with 201 stainless steel, 316 stainless steel is suitable for use in humid environments. It is not easy to rust in contact with water. It can be used in damp/salt/rain water and other environments, but it is also suitable for seawater and chemical media. It is the stainless steel material of choice for medical and heavy industrial equipment. 304 stainless steel cannot be used for sea water and chemical media. 316 stainless steel is added with metal materials on the basis of 304 stainless steel, which has better toughness, higher density and more corrosion resistance than 304. Manufactured by precision cold forging (no cutting), all performance indicators are stronger than other ordinary stainless steel. The performance level of our hexagonal bolts reaches A4-70, and the tensile strength of the bolt material reaches 700MPa.
