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 Fastener Fully Threaded Threaded Rods Introduction
The threaded rods is a mainstream detachable fastening connection component, consisting of a threaded rod with a head. It is often used in combination with nuts and washers, relying on the pre-tightening force of the thread to fix components. It is widely applied in industries such as pipeline flanges, pressure vessels, mechanical equipment, and steel structures.According to appearance, it can be classified into types such as external hexagon, internal hexagon, and countersunk. For high-pressure pipeline conditions, hexagonal high-strength bolts and full-threaded studs with matching nuts are mainly used; according to material, it can be divided into carbon steel and stainless steel. Carbon steel is divided into grades 4.8, 8.8, 10.9, and 12.9, with higher grades having stronger tensile and compressive properties. Alloy steel of grades 10.9 and 12.9 undergoes quenching and tempering heat treatment and is suitable for high-temperature and high-pressure pipe fittings and pressure vessels; 304 and 316 stainless steel bolts are resistant to acid and alkali corrosion and are mostly used in pipelines with corrosive media in the chemical industry.The production process includes raw material cutting, forging/rolling forming, turning and fine processing, heat treatment, thread processing, surface anti-corrosion treatment, inspection and storage. The thread strictly follows national and American standards, and after processing, it is inspected through gauge inspection. The product surface can be blackened, galvanized, or coated with Teflon for rust prevention. It is not prone to rust and loosening for a long time. The bolt is convenient for disassembly and assembly, can be repeatedly disassembled for maintenance, and is more convenient for later maintenance and replacement compared to welding connections. It is an indispensable standard fastener for pipeline and equipment assembly.

316L Fastener Fully Threaded Threaded Rods Product Processing
Key Product Processing Steps:
* Raw Material Selection: Common materials include low carbon steel, alloy steel (ASTM A193 B7), or stainless steel for high-load or corrosive environments.
* Straightening: Raw steel coils are straightened before threading to ensure axial alignment.
* Threading Method:
* Raw Material Selection: Common materials include low carbon steel, alloy steel (ASTM A193 B7), or stainless steel for high-load or corrosive environments.
* Straightening: Raw steel coils are straightened before threading to ensure axial alignment.
* Threading Method:
* Thread Rolling (Common): Cold-forging process where hardened dies press into the steel, displacing material to form threads without cutting. This creates higher fatigue strength.
* Thread Cutting: Cutting into the metal, usually for larger diameters or special projects.
* Cutting to Length: Rods are produced in long lengths (e.g., 1–3 meters) and cut down to standard sizes like 1-foot or 6-foot,or custom lengths.
* Chamfering: Ends are beveled to allow for smooth installation of nuts and prevent damaged thread entry.
* Surface Treatment/Finishing:

* Surface Treatment/Finishing:
* Plain Finish: Oiled or untreated.
* Zinc Plating: For corrosion resistance in dry environments.
* Hot-Dip Galvanizing (HDG): Heavy coating for outdoor/coastal applications, often requiring centrifugal spinning to ensure threads are not blocked by excess zinc
