What is the S45c steel material properties?

 S45c steel /CK45 or AISI 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.

Characterised by good strength and impact properties, with good machinability and reasonable weldability in the as supplied condition.

S45C steel 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.

The Production Process Of Chrome Plated OD Tubing

  Chrome plated od tubing is also known as chrome plated hollow bar ,chrome plated tubing a very important part for producing hydraulic piston rods and roller shafts in various machines. The biggest advantage of chrome plated od tubing than normal chrome plated rod is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the hydraulic cylinders . The Production Process Of Chrome Plated OD Tubing Step 1. Get the steel tubes heat treated as per customers’ request. Step 2. Cutting the raw material hollow rod into lengths Step 3. Straightening the hollow rods Step 4. Peeling on the steel hollow rods Step 5. Straightenning Step 6. Grinding the steel hollow rods Step 7. Straightening the ground hollow bars. Step 8. The second grinding process Step 9. Polishing on outer diameter surface Step 10. Chrome plating Step 11. Final polishing Step 12. Final inspection Anbao Hydrualic is a professional  chrome plated ID tubing and hollow bar m
