Liaoning OEM Stainless Steel 303 304 316 CNC Precision Machining Casting Services for 303 304 316 Products

Liaoning-based manufacturing facilities have established themselves as leading providers of precision CNC machining and casting services for stainless steel components, specializing in grades 303, 304, and 316. These advanced manufacturing capabilities serve global OEM requirements with cost-effective, high-quality solutions that meet international standards.

Stainless Steel Material Properties

Stainless Steel 303 represents the optimal choice for machining applications, featuring added sulfur that significantly enhances machinability while maintaining good mechanical properties. This free-machining grade delivers tensile strength of 620 MPa minimum and yield strength of 240 MPa minimum, making it ideal for high-volume production of precision components.

Stainless Steel 304, the most widely used austenitic stainless steel, contains 18% chromium and 8% nickel. This composition provides excellent corrosion resistance, good formability, and outstanding welding characteristics. With tensile strength reaching 515 MPa and yield strength of 205 MPa, 304 stainless steel maintains its properties across a wide temperature range.

Stainless Steel 316 offers enhanced corrosion resistance, particularly against chlorides and other industrial chemicals, through the addition of 2-3% molybdenum. This grade demonstrates superior performance in harsh environments while maintaining excellent strength and toughness at both high and low temperatures.

Advanced Manufacturing Capabilities

Liaoning manufacturing facilities employ state-of-the-art CNC machining centers capable of handling complex geometries and tight tolerance requirements. Multi-axis machining technology enables complete component processing in single setups, reducing production time and ensuring dimensional accuracy within ±0.005 mm for critical features.

The integration of precision casting processes with CNC machining creates a comprehensive manufacturing solution. Investment casting techniques produce near-net-shape components with excellent surface finish, while sand casting methods accommodate larger parts and lower volume requirements. Secondary CNC machining operations ensure critical dimensions and mounting surfaces meet precise specifications.
