316 Stainless Steel Hex Bar for Marine Grade Fastener Manufacturing

Product Description

Product Description

Product Overview

316 stainless steel hexagon bar is a six sided profile manufactured from high quality 316 austenitic stainless steel through hot rolling or cold drawing processes. It offers excellent corrosion resistance and good machinability, widely used in fasteners, fittings, valves, pumps and general engineering components.

Typical Process Flow: Melting → Conditioning → Hot Rolling → Annealing → Pickling → Cold Drawing → Straightening → Cutting
Available Surface Finishes: Hot rolled, cold drawn bright, peeled and polished, centerless ground

Applicable Standards

ASTM A276 / A479
EN 10058 / DIN 1017
EN 10278 / DIN 671
