OEM 1117 Free Cutting Steel Manufacturer & Supplier

Your Strategic Global Partner for High-Precision Machinability, Optimized Resulfurized Steel Solutions, and Industrial Performance Excellence.

What is AISI 1117 Free Cutting Steel?

Engineering the Future of CNC Precision and High-Speed Machining

Metallurgical Excellence

AISI 1117 is a low-carbon, high-manganese resulfurized steel designed specifically for maximum machinability. By controlling sulfur morphology into manganese sulfide (MnS) inclusions, we ensure broken chips and reduced tool wear.

  • Machinability Rating: 90% (of B1112)
  • Enhanced Surface Finish Quality
  • High-Speed Screw Machine Efficiency

Critical Applications

From complex hydraulic valves to automotive fasteners, 1117 steel provides the perfect balance of toughness and "free-cutting" ease. It is the gold standard for OEM manufacturers requiring tight tolerances.

  • Automotive Steering Components
  • Precision Fasteners & Studs
  • Hydraulic Fittings & Manifolds

Global Sourcing Demand & Market Dynamics

Navigating the Shift in High-Machinability Alloy Procurement

Supply Chain Resilience

In the post-pandemic era, global procurement managers are moving away from single-source dependencies. We provide a stable OEM supply chain for 1117 steel, ensuring JIT (Just-In-Time) delivery for European and North American manufacturing hubs.

Material Substitution Trends

Many industries are transitioning from leaded steels (like 12L14) to resulfurized non-leaded options like 1117 to meet strict RoHS and environmental regulations without sacrificing significant machining speed.

Cost-Efficiency in Scale

By leveraging our large-scale production facilities in Shandong, we offer competitive "Direct-from-Factory" pricing, reducing the Total Cost of Ownership (TCO) for Tier 1 and Tier 2 industrial suppliers.

Technical Roadmap & Future Outlook

How Material Science is Redefining 1117 Steel Performance

2023 - 2024

Micro-Alloying Optimization

Integration of controlled Nitrogen and Silicon levels to enhance the grain structure of 1117 steel, providing better case-hardening response for gears and shafts.

2025 - 2026

AI-Driven Smelting

Implementation of AI sensors in our blast furnaces to predict and control MnS inclusion distribution with 95% accuracy, ensuring zero "hard spots" during machining.

2027+

Carbon Neutral Steel

Transitioning toward hydrogen-based DRI (Direct Reduced Iron) to offer "Green 1117 Steel" for the global EV and renewable energy sectors.

Localization Support & Compliance Assurance

Bridging the Gap Between Chinese Production and Global Quality Standards

Standard Alignment

Our 1117 steel meets and exceeds ASTM A108 (Cold Finished) and ASTM A29 (Hot Rolled) specifications, ensuring full compatibility with international engineering prints.

Third-Party Verification

Every shipment comes with a certified Mill Test Report (MTR). We also support on-site inspections by SGS, BV, and TUV to guarantee chemical composition and mechanical properties.

Global Logistics

Dedicated logistics teams handle customs clearance, duty-paid delivery (DDP), and localized warehousing support in key markets like Vietnam, Mexico, and Germany.

Frequently Asked Questions (FAQ)

Expert Insights into 1117 Steel Specification and Machining

How does 1117 compare to 1018 steel?
While 1018 is a general-purpose carbon steel, 1117 contains higher Manganese (1.00-1.30%) and Sulfur (0.08-0.13%). This makes 1117 significantly easier to machine and provides a superior surface finish in screw machine operations.
Can 1117 steel be case hardened?
Yes. Due to its low carbon content (0.14-0.20%), 1117 is an excellent candidate for carburizing or case hardening, allowing for a hard, wear-resistant outer shell with a tough, ductile core.
Is 1117 steel weldable?
1117 is considered weldable, but the high sulfur content can lead to "hot shortness" or weld cracking. We recommend using low-hydrogen electrodes and careful pre-heating/post-heating procedures if structural welding is required.
What forms do you supply 1117 steel in?
As a leading OEM supplier, we provide 1117 steel in cold-drawn round bars, hexagonal bars, square bars, and customized hot-rolled plates or coils depending on your manufacturing requirements.
