Amarex manufactures machined stainless steel parts and carbon steel components for automotive, electrical, instrumentation and industrial OEMs. We CNC machine stainless grades 303, 304, 316, 316L, 410 and 430 plus low and mild carbon steels, producing fasteners, shafts, fittings and turned components to tight tolerances with ISO 9001:2015 certified quality management (Mumbai office).
Steel Alloys
Steel Grades We Machine
Stainless grade selection balances corrosion resistance, machinability and cost. These are the grades we run routinely, with others available against your specification.
Stainless and carbon steel forged blanks also machined (see Machined Forgings).
Steel Components We Manufacture
Typical machined stainless and carbon steel parts we supply to customer drawings:
- Precision fasteners and machined fastener components
- Stainless steel turned components and fittings
- Shafts, pins and wear parts
- Instrumentation components in SS 303/304/316
- CNC steel parts for automotive and industrial assemblies
| Grade | Key properties | Typical applications |
|---|---|---|
| SS 303 | Free-machining stainless - fastest to cut | Precision turned components, fittings |
| SS 304 | General-purpose corrosion resistance | Fasteners, housings, general components |
| SS 316 / 316L | Superior corrosion resistance incl. marine/chloride | Marine, chemical and critical fittings |
| SS 410 / 430 | Martensitic/ferritic - hardness and wear | Shafts, wear parts, magnetic applications |
| Low & mild carbon steel | Strength and economy in high-load parts | Automotive and general industrial components |
| Alloy steels (on request) | Enhanced strength/toughness | Load-bearing machined components |
How We Machine Steel - Turning, Threading & Gauged Accuracy
Steel components are CNC turned and milled with thread gauges and calibrated instruments verifying every critical feature. Stainless and carbon steel forged blanks are machined where strength demands it, and every part ships dimensionally verified with material certification.
CNC turning & milling
stainless steel cnc machining parts to tight tolerances
Threading
gauged internal and external threads on fasteners and fittings
Forged blank machining
stainless and carbon steel forgings machined to drawing
Inspection
thread gauges and calibrated instruments on every batch
Steel & Stainless Machining Process
Steel and stainless components are bought on thread accuracy and surface condition. Every critical thread is gauged and every batch is verified on calibrated instruments before it is packed.
303, 304, 316 and 316L stainless and carbon steel selected by duty
CNC turned and milled to tight tolerances from bar and forged blanks
Internal and external threads cut and gauged on fasteners and fittings
Thread gauges and calibrated instruments verify every batch
Why Choose Stainless & Carbon Steels
Steel remains the default for strength; stainless adds the corrosion resistance that keeps components serviceable for decades.
Corrosion resistance
304 for general service, 316L where chlorides attack
Strength & durability
handles loads brass and aluminum cannot
Machinability options
free-machining 303 keeps precision part costs down
Temperature tolerance
stable properties across wide service ranges
Cost-effective carbon steels
strength per rupee for high-load, non-corrosive duty

Frequently Asked Questions
We machine SS 303, 304, 316, 316L, 410 and 430 as standard, plus low and mild carbon steels and alloy steels on request – all to customer drawings.
Yes. We manufacture and export machined stainless steel parts to OEMs across the USA, UK, Europe, with material certificates on every batch.
SS 316 adds molybdenum, giving markedly better resistance to chlorides and marine environments. 304 suits general service; 316/316L is the choice where salt or chemicals attack.
Yes. Stainless steel turned components – fittings, fasteners, shafts and instrumentation parts – are core work, CNC turned and gauged to drawing.
Yes. Alloy steel machined components are produced on request where enhanced strength and toughness are needed, with material certification supplied.
Yes. Stainless and carbon steel forged blanks are machined to drawing where strength demands forged grain structure – see our Machined Forgings page.
