Are you looking for a stainless steel metal parts supplier with full in-house capability? Nanpi Xinjiuxinji Hardware Manufacturing has served global clients since 1999. We are located in Nanpi County, Hebei Province, China. Our factory sits close to Beijing and Tianjin. That location keeps logistics fast and reliable.

We cover design, prototyping, production, and finishing under one roof. Our team of 120 people includes 19 experienced engineers. They turn your drawings into finished stainless steel parts. We have delivered over 70,000 different types of custom metal parts so far.

Our Stainless Steel Manufacturing Capabilities

We handle the complete stainless steel fabrication process in-house. One supplier means fewer hand-offs and fewer quality gaps. Here are the core processes we run every day.

• Stamping. We operate 40+ stamping presses from 60T to 400T. The largest single-point press reaches 400T. It forms thick stainless steel blanks with consistent quality.
• Deep drawing. We deep draw stainless steel into cups, housings, and enclosures. Complex shapes stay uniform across long production runs.
• Laser cutting. Our 6kW laser cutter delivers clean edges on stainless steel. It handles complex outlines and tight dimensional requirements.
• Bending and forming. CNC press brakes fold parts to exact angles. Every batch keeps the same geometry.
• Welding. CNC welding equipment joins stainless parts with strong, clean seams. We use TIG and MIG for most applications.
• CNC machining. We mill, drill, and turn features that forming cannot create. This adds threads, slots, and fine details.
• Surface finishing. We brush, polish, and passivate stainless steel parts. This improves corrosion resistance and appearance.

Stainless Steel Grades We Work With

Stainless steel comes in many grades. Each grade fits different working conditions. Our engineers help you choose the right one.

• 304 stainless steel. The most common grade for general parts. It suits enclosures, brackets, and kitchen-related components. It resists corrosion well in normal environments.
• 316 stainless steel. It contains molybdenum for extra corrosion resistance. It is ideal for marine, chemical, and coastal use.
• 430 stainless steel. This ferritic grade offers good formability at lower cost. It works well for decorative parts in mild environments.
• 201 stainless steel. A budget-friendly option for moderate demands. It helps you control cost without losing basic performance.

Material choice drives both performance and cost. We match the grade to your application and budget. You get parts that work and stay competitively priced.

Recent Project Cases

Real projects show how we work. Here are three recent examples from our shop floor.

Deep-drawn stainless steel housing for an electronics client. The client needed a 304 stainless enclosure for a control module. We combined deep drawing, laser cutting, and spot welding. All units met the required dimensional limits. We delivered 50,000 units in 4 weeks. The customer has placed three repeat orders since.

Stainless steel band clamp for an industrial equipment maker. The client needed a strong, adjustable clamp for heavy-duty use. We stamped the band from stainless steel and bent the mounting plate. We riveted the over-center latch in place for fast tightening. We delivered 20,000 clamps in four weeks. Rework stayed below 0.5 percent.

CNC-machined stainless steel pins for a medical device maker. The client needed stepped pins with a center flange for a medical instrument. We turned them on CNC lathes and ground them to the required finish. All 30,000 pieces shipped on schedule. The customer praised the stable quality across batches.

FAQ

What stainless steel grades do you work with? We work with 304, 316, 430, 201, and more. Our engineers recommend the best grade for your application and budget.

What should I prepare before contacting a stainless steel metal parts supplier? Send your drawings or a rough idea of the part. Our engineers will confirm feasibility and give a clear quote.

Do you support prototyping? Yes. We build prototypes before mass production. This lets you verify fit, finish, and function first.

What is your minimum order quantity? MOQ depends on part size and process. Small prototype orders are welcome. Send us your drawing for a clear answer.

Can you make parts from my drawings? Yes.
