S45C cold drawn bar and S50C carbon steel plate. Precision bandsaw-cut with no MOQ, mill test reports and global shipping from Malaysia.
Medium-carbon steels give more strength and wear resistance than mild steel without the cost of low-alloy grades. E STEEL SDN BHD supplies S45C as cold drawn, polished bar and S50C as plate, both cut to size with no MOQ.
E STEEL SDN BHD supply S45C Cold Drawn Bar | Polish Bar with h9 tolerance to fullfill market demand. Size Range from Diameter 10mm to 100mm. Beside of 45c Carbon steel, we do have Oil Hardening Steel 1.2510 / O1 steel with polish condition with tolerance h8.
Steel that is drawn passes through a series of dies to achieve a desired shape is known as drawn steel. … Cold refers to the drawn steel being manufactured at room temperature, which requires additional pressure to shape the steel, but gives the steel extra qualities and visually aesthetic appearance.
1045 Carbon Steel 1045 is a medium tensile low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 600 – 950 Mpa and Brinell hardness range 179 – 280. in either condition. Characterised by good strength and impact properties, with good machinability and reasonable weldability in the as supplied condition. 1045 has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. It can however be successfully flame or induction hardened in the as supplied condition resulting in surface hardnesses of up to Rc 54 – Rc 60 depending upon quenching medium employed, type of set up, section size etc. Core strengths will remain as supplied. It does not however respond satisfactorily to nitriding due to a lack of suitable alloying elements. 1045 is used extensively by all industry sectors for applications requiring more strength and wear resistance than the low carbon mild steels can provide and the higher strength of the low alloy high tensile steels is not necessary, plus those applications requiring flame or induction hardening.
Cold Rolled Steel is ideal for projects where precision is essential. The metal is easily formable for moderate draw applications. This makes it ideal for use in many home appliances and metal furniture. Metal filing cabinets and school lockers are commonly made of this metal.Typical applications are: Axles Various, Bolts, Connecting Rods, Hydraulic Clamps and Rams, Pins Various, Rolls Various, Studs, Shafts, Spindles etc.
Cold finished steel is essentially hot rolled steel that has further processing. Cold finished steel, also known as cold rolled, is typically produced as turned bars or cold drawn bars.
It’s important to note that the main difference between hot rolled and cold rolled steel is one of process. “Hot rolling” refers to processing done with heat. “Cold rolling” refers to processes done at or near room temperature. … It may seem obvious, but some types of steel are better suited for certain applications.
AISI 1050 Steel Nearest Equivalent : S50C, 1.1730, 1191, UNS G10500, AISI 1050 steel is a medium-carbon, cold rolled steel containing approximately 0.50% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 58. Soft annealed high carbon steel is intended for applications requiring moderate forming, while soft spheroidized annealed product is intended for applications requiring maximum cold forming. This grade of steel is used for the manufacture of blades, brackets, brake discs, clips, clutches, springs, washers and gears and for a wide range of applications that can make use of its good combination of mechanical properties.

S50C’s versatility makes it ideal for:
This grade is readily welded with the correct procedure. Welding in the through-hardened or flame or induction-hardened conditions is not recommended.
Low-hydrogen electrodes are recommended together with preheat at 300-800ºF (150-430ºC to be maintained during welding, Cool slowly in sand or ashes and stress relieve where possible. It may be that in certain instances normalizing may be called for after welding.
Bandsaw technology ensures minimal kerf loss and clean, burr-free edges.
Cut to the size your job needs. No minimum order quantity.
Mill test reports (MTRs) for traceability.
Fast air and sea shipping with real-time tracking.
Yes – S50C offers higher strength but requires careful heat treatment for similar ductility.
Yes, with preheating and post-weld annealing to avoid cracking.
3–5 business days for most orders.
