UNS S38815 Stainless Steel
S38815 stainless steel is a high-strength, high-corrosion-resistant stainless steel that is often used to manufacture parts in high-temperature and corrosive environments. Its composition includes metal elements such as aluminum, molybdenum, niobium and titanium, giving it excellent mechanical properties and chemical stability.
S38815 stainless steel has excellent corrosion resistance, especially in high temperature, acidic and chloride environments. It can withstand high temperatures up to 1000°C and can be used for a long time in strong acid and alkali environments. These properties make S38815 stainless steel an important material in the chemical, marine engineering, power and nuclear industries.
The UNS S38815 materials produced by our company include plates, rods, tubes, steel strips, wires, forgings, forged pipes, forged plates, forged rods, round bars, plates, sheets, seamless pipes, welded pipes, round steel, wire, etc.

Heavy Forging Press Capacity
Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat Treatment Capability
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
Heavy Shaft Machining
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Ring Forging Machining
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
Cylindrical Forging Machining
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Inspection & Testing
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Packing & Delivery
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
