UNS S31600 Pipe,UNS S31600 High Performance Stainless Steel Seamless Pipe in Petroleum Refining
UNS S31600 is a molybdenum-containing austenitic stainless steel with greater resistance to general corrosion and pitting/crevice corrosion than conventional chromium-nickel austenitic stainless steels such as 304, as well as higher creep, fracture stress, and tensile strength at elevated temperatures. In addition to its excellent corrosion resistance and strength properties, 316 has excellent fabricability and formability. It is also known as marine grade stainless steel.

Benefits:
- Higher creep stress and rupture properties when compared with 304
- Ideal for high temperature service
- Overcomes sensitization and intergranular corrosion concerns
- Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
- Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
- Excellent mechanical properties
Applications:
316 Stainless Steel Seamless Tube is a kind of hollow long round steel, which is widely used in industrial pipelines and mechanical structural parts for petroleum, chemical, medical, food, light industry, mechanical instrumentation and so on. In addition, it is lighter in weight with the same bending and torsion strength, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used in the production of a variety of conventional equipment, gun barrels, shells, etc..
Production Process:
Quality Control:
1. Quality control of raw materialsFirst, secondary inspection of raw materials
Our raw materials come from large factories such as Baosteel and TSINGSHAN. Each batch of raw materials requires MTC and PMI. After the raw materials arrive, we conduct PMI and other inspections again to ensure that they meet the requirements
2. Quality control during productionSecond, traceability of the production process
Each process is equipped with advanced production equipment, and is supervised by experienced engineers and technicians. Each link is supervised by professional qc inspectors and photographed for archiving. The entire process uses process cards to ensure accuracy and traceability.
3. Quality control before shipmentThird, 100% inspection before shipment
MTSCO has professional QC team to conduct a series of inspections and experiments on the Pipes, including routine appearance, PMI, size, quantity, and other inspections. At the same time, we also conducts mechanical testing, hardness testing, UT, ET, HT and other tests. In addition, we also accept third-party inspection, such as SGS, TUV, and BV.
Before shipping, we use appropriate and safe packaging methods and take measures such as container reinforcement to ensure that your goods are delivered to you in good condition.
