HYT, a trusted metals pipe supplier, offers a range of 316/316L stainless steel pipes, with an inventory tailored to meet industry requirements. These grades of austenitic stainless steel offer many of the same characteristics and advantages as 304/304L, but they have an added element that elevates their corrosion resistance: molybdenum.
At HYT, we prioritize the quality and reliability of our products, with most of our inventory being dual-grade specified or with multiple specifications, including ASTM, ASME, MIL-P, and the European standard PED 97/23EC.
Common Industry Applications for 316/316L Stainless Steel Pipe
316/316L stainless steel pipe can withstand elevated temperatures longer than grade 304/304L, has better corrosion resistance, and offers excellent weldability. It has many applications:
Chemical: chemical containers, pressure vessels, and industrial equipment
Water treatment: woven or welded screens for water filtration
Pulp and paper: used in paper machines to avoid iron contamination.
Automotive: threaded fasteners, springs, and furnace parts
Medical: medical equipment and orthopedic implants
Dental: dental implants, orthodontic appliances, and various dental instruments
Semiconductor: semiconductor manufacturing equipment and cleanroom environments
Food processing: food preparation surfaces, equipment, and appliances
Aerospace: aircraft structures, fasteners, turbine blades, and exhaust systems

Q: What are the advantages of HYT's SS316L steel pipe?
A: Our SS316L steel pipe uses imported raw materials and strictly controls the molybdenum content at 2.1-2.5% to ensure excellent corrosion resistance. The product is cold rolled and solution treated, with a high inner wall finish, suitable for food and pharmaceutical grade applications. We provide various specifications from 6mm to 630mm, and non-standard customization is acceptable.
Q: What is the difference between SS316L and ordinary 304 steel pipe?
A: SS316L contains 2-3% molybdenum elements, which has better chloride corrosion resistance than 304 steel pipe, and is particularly suitable for marine environment and chemical applications. The carbon content of our products is controlled below 0.02%, and the welding performance is better.
Q: How to ensure product quality?
A: We provide third-party test reports for each batch of products, implement ASTM A312 standards, and conduct 100% weld X-ray flaw detection. All products undergo strict factory inspection to ensure compliance with international standards.
Q: What is the minimum order quantity?
A: The minimum order quantity for conventional products is 1 ton, and customized products support small batch trial orders of 500kg. We have sufficient inventory and conventional products can be shipped within 72 hours.
