Mild Steel Parts FAQ
What is mild steel and why use it for machined parts?
Mild steel (low-carbon steel) is the most cost-effective engineering material for structural and non-critical components. Mild steel offers excellent machinability, good ductility, and reasonable strength. It is used for brackets, mounting plates, shafts, housings, and general engineering components where cost is a key factor.
What are the advantages of mild steel over other materials?
Mild steel offers lowest cost per kilogram of machined material, excellent machinability (fast cutting, low tool wear), high ductility (good for forming and bending), good weldability, and proven engineering performance. Mild steel is ideal for low-stress, non-critical applications where cost reduction is priority. Surface treatment (paint, plating, coating) provides corrosion protection.
What tolerances can you hold on mild steel parts?
Mild steel machines to good tolerances with low machining forces. Standard CNC machining achieves ±0.05mm on general features. High-precision mild steel machining achieves ±0.02mm. Mild steel has minimal thermal distortion during machining — ideal for precision work.
What grades of mild steel do you work with?
We supply 1018 (most common, excellent machinability, case-hardening capable), 1020 (slightly higher carbon, good strength), 1045 (medium carbon, higher strength, pre-hardened available), and A36 (structural steel, lower cost). All grades are readily available and cost-effective.
What is the typical lead time for mild steel parts?
Mild steel is widely available with fast machining. Single-off parts typically require 1–2 weeks. Stock material is readily available in rod, plate, and bar. Production runs benefit from high machining speeds, reducing per-unit cost significantly. Expedited jobs available.
Can you surface treat mild steel for corrosion resistance?
Yes. Mild steel is easily treated with paint, powder coating, plating (zinc, nickel), or chemical coatings. We manage finishing through our supplier network — specify your finish requirement and environment (indoor, outdoor, wet, salty) in your quote request.
