Components Materials of Stainless Steel Screw Jacks

Stainless steel screw jacks are engineered for corrosive, wet, or hygienic environments by using specific grades of 304 or 316 stainless steel for nearly all exposed parts, paired with wear-resistant bronze for internal gearing. While most external parts are stainless, critical internal components often use specialized alloys like bronze to prevent mechanical failure such as galling or seizing.
