Stainless Steel Rod/Bar
Changjin is one of the prominent trader, supplier and manufacturer of SS Round Bars, which is known for its excellent galling resistance, even at elevated temperatures, where chips will be tough and stringy, therefore chip curlers and breakers are important. These Stainless Steel Square Bars maintains decent strength up to temperatures of 1800 Degree F and has oxidation resistance similar to that of other steels.
The general corrosion resistance of our Stainless Steel Flat Bars is between that of stainless steel and other alloys. Good transverse toughness properties of these Stainless Steel Threaded Bars are achieved by tight chemical composition control, low carbon content, and vacuum melting. The mechanical properties for the different tempers of these Stainless Steel Hollow Bars are obtained by cold working and not by heat treating.
Annealed material of our Stainless Steel Hexagonal Bars has a tensile strength and is used for deep and shallow formed parts. These Stainless Steel Triangular Bars has good resistance to oxidation at temperatures up to 1550 Degree F, but is not recommend for use above 1600 Degree F.

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.
