Common Stainless Steel Grades & Applications

Guide to Selecting Stainless Steel Grades & Manufacturing Processes

Step 1: Pick the right grade to match your stainless steel parts' performance needs

Corrosion-resistant applications: 316/316L → ideal for marine and chemical stainless steel components
General-purpose projects: 304/304L → versatile, cost-effective stainless steel parts
High-load structural parts: 17-4PH → ultra-strong stainless steel components
Wear-resistant parts: 420 → durable stainless steel parts for cutting use
High-precision small parts: 303 → optimized machinability for miniature parts

Step 2: Match the optimal manufacturing process

316/316L: CNC machining for precision; investment casting for complex parts
304/304L: Sheet metal for enclosures; CNC for tight-tolerance components
17-4PH, 420, 303: CNC machining delivers superior accuracy & surface finish
Rapid prototyping: Stainless steel 3D printing supports fast iteration

Our Custom Stainless Steel Manufacturing Capabilities

Our CNC machining produces ultra-precise stainless steel parts with tolerances up to ±0.001 mm and surface roughness Ra 0.4–3.2 μm. Engineered for stainless steel components used in medical, aerospace, and high-load equipment, this process ensures stability, anti-oxidation performance, and consistent quality across long production runs. Swiss-type lathes further enhance precision for micro stainless steel components with strict concentricity requirements.

Precision Stainless Steel CNC Machining

Ideal for complex stainless steel parts, our investment casting delivers near-net-shape stainless steel components with reduced machining and lower per-unit costs. Compatible with 304, 316, 316L, and other corrosion-resistant alloys, it is widely used in valve bodies, pump parts, and intricately shaped stainless steel components.

Stainless Steel Investment Casting

Our sheet metal services produce lightweight, durable stainless steel parts including enclosures, brackets, and panels. With material thickness from 0.5–12 mm and tight tolerance control, this custom stainless steel fabrication method supports fast lead times and high repeatability for structural stainless steel components.

Stainless Steel Sheet Metal Fabrication

Stainless Steel 3D Printing

For rapid prototyping and low-volume stainless steel parts, 3D printing enables full design freedom without tooling. It supports all major stainless steel grades and produces functional stainless steel components with tolerances ±0.1–±0.25 mm, accelerating time-to-market for new products.
