A4 Stainless Steel Internally Threaded Dowel Pin

A4 Stainless Steel Internally Threaded Dowel Pin combine the dimensional form of GB/T 120.1 / ISO 8735 with the material properties of grade A4-80 (316): superior, including marine and chloride environments, largely non-magnetic, service range approx. -200 °C to +400 °C. This page summarizes the grade data, its corrosion behavior in service, the comparable grades, and the sizes supplied.

Why Choose A4 Stainless Steel for Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100)

Specified for marine, coastal and chemical applications. For internally threaded dowel pin — gb/t 120.1 / iso 8735 (series 100), this matters when superior, including marine and chloride environments is the primary requirement.

Mechanical & Physical Properties

Galvanic & Galling Considerations

Two important notes for stainless internally threaded dowel pin — gb/t 120.1 / iso 8735 (series 100): (1) stainless can gall on stainless threads under load — use a thread lubricant or anti-galling compound, especially for M6 and below; (2) when joined to aluminum or galvanized steel, stainless can drive galvanic corrosion of the less-noble metal in wet service — isolate with a coating or sleeve where appropriate.

Comparable Grades

For Internally Threaded Dowel Pin — GB/T 120.1 / ISO 8735 (Series 100), 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.
