Clamping Handle Screw (Long) manufactured in A4 Stainless Steel (A4-80 (316)) are dimensioned to DIN 6336 / GN 313. The sections below give the mechanical and physical properties of the grade, its behavior in corrosive and elevated-temperature service, and the full size table.
Why Choose A4 Stainless Steel for Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044)
Specified for marine, coastal and chemical applications. For clamping handle screw (long) — din 6336 / gn 313 (series 044), this matters when superior, including marine and chloride environments is the primary requirement.
Mechanical & Physical Properties
| Grade designation | A4-80 (316) |
|---|---|
| Magnetic response | Largely non-magnetic |
| Service temperature | approx. -200 °C to +400 °C |
| Corrosion characteristic | Superior, including marine and chloride environments |
Corrosion Behavior in Service
A4 (316) adds 2–3% molybdenum to the A2 (304) composition, which dramatically improves resistance to chloride-pitting corrosion. For Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044) in marine, coastal, swimming-pool or food-processing environments, A4 is the default selection.
Comparable Grades
For Clamping Handle Screw (Long) — DIN 6336 / GN 313 (Series 044), the alternative stainless grade is A2 (304). A2 (304) suits general indoor and outdoor service; A4 (316) adds molybdenum for marine and chloride environments. Where higher strength matters more than corrosion, switch to plated alloy-steel class 8.8 or 10.9.
