Stainless Steel Parts – Detailed Technical Description
Stainless Steel Parts are engineered components manufactured using globally certified Stainless Steel materials, designed to resist corrosion, moisture, and high-temperature environments. These parts are widely used in Automotive Assemblies, Marine Fittings, Electrical Terminals, Sanitary Components, Valves, Pumps, Pneumatic Fittings, Food-Grade Equipment, Transformers, and Chemical Processing Units. Our Stainless Steel Parts are produced in various shapes including round, hex, square, tubular, slotted, and custom-profile geometries. With decades of export experience, we offer flexible production, customised material selection, custom packaging, private labelling and value engineering suggestions for design improvement and cost optimisation.
Stainless Steel Machined Parts
Stainless Steel Machined Parts are manufactured through milling, drilling, turning, threading and tapping processes on advanced CNC machines. These machined components require high dimensional accuracy and surface finish (Ra 0.4 – Ra 1.6). The machinability varies by grade, with 303 being the easiest and 316 being more challenging due to its work-hardening behaviour. Our engineering team optimises speeds, feeds, coolant systems and tool materials to achieve precise output. These machined parts serve industries that need high-strength, corrosion-resistant, and hygienically safe components including pharmaceuticals, biotech, dairy equipment, and instrumentation assemblies.
Stainless Steel CNC Machining
Stainless Steel CNC Machining refers to automated, computer-controlled cutting and shaping of Stainless Steel bars, billets or forgings to produce complex profiles. CNC machining ensures repeatability, tight tolerances, and error-free production for components with intricate geometries such as threads, undercuts, chamfers, grooves, cavities, and precision bores. Our multi-axis CNC machines support high-speed machining cycles and deliver consistent quality for global OEM requirements. CNC machining is particularly beneficial for Stainless Steel components used in Aerospace, Medical Implants, Marine Equipment, and High-Pressure Hydraulic Systems.
Stainless Steel Turned Components
Stainless Steel Turned Components are produced on CNC turning or automatic lathe machines, ideal for round, stepped, threaded and concentric geometries. These components include bushings, spacers, shafts, pins, connectors, adapters, couplings, ferrules, and sleeve-type parts. Turned components require smooth surface finish, precise OD/ID control, and perfect thread profiles as per ISO Metric Threads, UNF, UNC, NPT, BSPT, BSPP, Metric Fine Threads, and custom forms.
304 Stainless Steel Parts
304 Stainless Steel Parts represent one of the most widely used product categories due to availability, cost-effectiveness and balanced performance. These parts offer excellent corrosion resistance, food-grade compliance, and non-magnetic properties. They are ideal for kitchen equipment, industrial fittings, architectural hardware, HVAC, and general engineering applications. High machinability of 304 allows complex CNC operations while maintaining structural integrity.
316 Stainless Steel Parts
316 Stainless Steel Parts are known for superior corrosion resistance in marine, acidic, and chloride environments. The presence of molybdenum (Mo) enhances pitting resistance, making 316 essential for Chemical Plants, Marine Hardware, Pharmaceutical Equipment, and High-Humidity Applications. These parts maintain mechanical strength even at elevated temperatures and have excellent weldability.
AISI 304 and 316 CNC Machined Components
AISI 304 and 316 CNC Machined Components combine material durability with precision CNC machining. These components are widely used in export markets such as USA, UK, Canada, Australia and Europe where strict quality certifications like RoHS, REACH, DFARS and ASTM compliance are mandatory. The combination of CNC machining accuracy and proven Stainless Steel grades ensures mechanical reliability, leak-proof assembly, and long service life.
Stainless Steel Screw Machine Parts
Stainless Steel Screw Machine Parts are manufactured on Swiss-type automatic lathes or high-speed screw machines for small, intricate and repetitive components used in Electronics, Connectors, Pneumatics, Sensors, and Valve Assemblies. These parts require exceptional concentricity, smooth threading, and burr-free finish for seamless assembly into final products.
