Ball pressure screws without head M24/35

Grade 1.4305 is a sulphurised austenitic stainless steel of the A1 type. It is specifically intended for machining. Due to its high sulphur content of up to 0.35 per cent, this material has lower corrosion resistance than comparable stainless steels with a typical sulphur content of no more than 0.015 per cent. It is not suitable for use in non-oxidising acids and media or in chloride-containing environments (such as marine environments, etc.).

Tempered steel is steel that is given high tensile and fatigue strength through tempering. The toughness is determined by the relationship between hardness and temperature of the subsequent tempering process. It is a transformation hardening in which the ratio of strength to toughness is specifically influenced.
