A4 Stainless Steel Internally Threaded Dowel Pin

Internally Threaded Dowel Pin manufactured in A4 Stainless Steel (A4-80 (316)) are dimensioned to GB/T 120.1 / ISO 8735. 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 Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 099)

Specified for marine, coastal and chemical applications. For internally threaded dowel pin — gb/t 120.1 / iso 8735 (series 099), this matters when superior, including marine and chloride environments is the primary requirement.

Mechanical & Physical Properties

Corrosion Behavior in Service

A4 (316) adds 2–3% molybdenum to the A2 (304) composition, which dramatically improves resistance to chloride-pitting corrosion. For Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 099) in marine, coastal, swimming-pool or food-processing environments, A4 is the default selection.

Comparable Grades

For Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 099), 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.
