Carbon Steel Bar

Available Grades

A36 / SS400 Mild Carbon Bar: Most popular general carbon grade, ultra-good weldability and ductility, ideal for building structural frames, common brackets and welded parts.
AISI 1018 / 1020 Low Carbon Bar: Fine surface cold drawn grade, easy bending and threading, widely used for standard fasteners, pins and general machined components.
AISI 1045 / C45 Medium Carbon Bar: Higher hardness and tensile strength, heat treatable, perfect for shafts, gears and medium-load mechanical spare parts.
Q235B Hot Rolled Carbon Bar: Economical domestic standard grade, abundant stock, stable performance for civil engineering and general structural fabrication.
1060 High Carbon Bar: High hardness and wear resistance, poor weldability, mainly made into simple tool blank and wear-resistant auxiliary parts.

Cost-Effective Raw Material: Simple chemical composition without precious alloy metal, lower material cost compared with alloy steel bar.
Excellent Welding & Formability: Low carbon content ensures easy welding, bending, stamping and cold forming for diversified processing demands.
Customizable Hardness: Medium & high carbon grades support quenching and tempering to improve surface hardness and load-bearing capacity.
Multiple Section Shapes Available: Stock round, square, flat, hexagonal carbon bars to fit diversified assembly and machining scenarios directly.
Strict Dimensional Accuracy: Standard hot rolled black surface and precision cold drawn bright surface, small tolerance, less machining allowance.
Good Natural Structural Stability: Uniform internal grain structure, no internal air hole, crack or impurity for long-term static service.

Building & Civil Structure: Used for building support frames, factory steel brackets, foundation embedded parts and outdoor structural supports.
General Mechanical Fabrication: Make machine base, connecting rod, standard shaft and common transmission parts for ordinary industrial equipment.
Industrial Fastener Production: Raw bar material for bolts, nuts, studs and rivets, fit general assembly and fastening usage.
Automotive Ordinary Components: Fabricate non-core automotive structural parts, chassis auxiliary brackets and vehicle welded accessories.
Hardware & Tool Blank: Process into hand tool blank, simple fixture, agricultural machinery parts and daily hardware components.
Container & Logistics Frame: Structural bar for logistics pallet frame, equipment container support and warehouse metal rack fabrication.

Cut Down Overall Procurement Budget: Far lower unit price than alloy steel, greatly reduce raw material cost for mass structural production.
Reduce Processing Barrier: Easy cutting, welding and drilling, compatible with ordinary workshop machines, no need for high-end processing equipment.
