Product Description

316L Introduction

Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.Grade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.

316L Full Thread Hex Head Bolt Introduction

Made of premium‑grade 316L austenitic stainless‑steel, the Full‑Thread Hex‑Head Bolt is an all‑threaded fastener engineered for harsh‑environment fastening work. 316L material contains molybdenum element, delivering excellent chloride‑resistance, anti‑corrosion property and low‑temperature toughness compared to regular 304 stainless‑steel bolts.Every workpiece is hot‑forged for hex‑head forming, then CNC‑rolled for complete continuous thread across the whole shank. Full‑thread design enables flexible fastening length adjustment and firm gripping in through‑hole and blind‑hole installation. The bolt surface keeps smooth brushed finish without burrs, with precise thread tolerance for smooth screwing and repeated disassembly.This hardware suits marine facilities, chemical‑industry pipelines, coastal engineering, food‑processing equipment and outdoor humid construction projects. Our factory supports customized diameter, length and surface treatment. Each batch will pass PMI material inspection, dimension‑check and anti‑defect screening. Reliable seawater‑rust resistance makes our 316L full‑thread hex‑head bolt your ideal heavy‑duty corrosion‑proof fastening choice.

Product processing

316L Full Thread Hex Head Bolt Product Processing

1.Raw‑material Inspection. Receive 316L stainless‑steel round bars and conduct PMI metal composition test to confirm material qualification, eliminate mixed‑material raw stock.2.Cutting‑off Process. Cut steel bars into fixed‑length blanks by automatic cutting machine, trim end‑face burrs.3.Hex‑Head Hot Forging. Heat metal blanks and forge integrated hexagonal head with heading machine, guarantee head structure without cracks.4.Whole‑shank Thread Rolling. Carry out thread‑rolling treatment for the entire bolt shaft to form complete full‑thread, inspect thread fit tolerance.5.Surface Polishing & Deburring. Grind sharp edges, clear rolling‑oil residue and metal chips off bolt surface, get neat brushed metallic texture.6.Corrosion‑resistance Testing. Sample‑test salt‑spray performance to verify the chloride‑resistant capacity of 316L stainless‑steel.7.Dimensional‑tolerance Check. Measure hex‑head width, bolt length, thread pitch and straightness one‑by‑one, sort out non‑conforming goods.8.Marking and Packing. Laser‑etch material grade and specification marks on hex‑head; pack bolts in moisture‑proof plastic bags and wooden cases for warehouse storage and export delivery.
