The production of thick stainless high strength steel fine blanked blanking parts pushes the boundaries of cold forming technology. This title combines three challenging variables: thickness, material hardness, and precision. High strength steel (HSS) and ultra-high strength steel (UHSS) are increasingly used in safety-critical applications to reduce weight without sacrificing strength. However, these materials have low ductility and high yield strength, making them prone to cracking during forming. When you add stainless properties (like in martensitic stainless steels) and thickness, the required blanking force becomes immense.
To successfully fine blank these parts, manufacturers must employ specialized tooling coatings (like TiAlN or DLC) to reduce friction and prevent galling, which is common when forming stainless steel. The process parameters-clearance between the punch and die, blank holder force, and lubrication-must be optimized to microscopic levels. The resulting blanking parts are used in high-stress environments, such as turbine components, high-pressure valve seats, and heavy-duty locking mechanisms. The ability to fine blank these materials means that parts can be produced with complex features, such as counterbores or extrusions, in the same stroke as the blanking operation. This "package" technology reduces the need for secondary machining, which is particularly difficult and expensive when dealing with hardened high-strength steels. The outcome is a cost-effective, high-performance component that meets rigorous industrial standards for tensile strength and dimensional stability.
