Import China Building Materials Spring Steel Ck75 — Buy in Bulk from Supplier in China

The product is China Building Materials Spring Steel CK75 supplied by Taian Henson Metal Co., Ltd. It is forged from top‑grade spring steel and is intended for components that must resist repeated loading. The material exhibits a tensile strength between 800 and 1300 MPa as stated in the supplier data. Available thicknesses range from thin sheets to heavy plates, allowing adaptation to diverse engineering drawings.

In the steel industry CK75 is defined by a carbon content of roughly 0.70‑0.80 % typical for this grade. After the standard quench‑and‑tempered heat treatment the hardness usually falls in the Rockwell C 45‑55 range, which is typical for spring applications. The alloy also contains manganese and silicon in amounts that are standard for improving fatigue resistance. These typical chemical and mechanical parameters align with ISO 683‑2 specifications for spring steel.

The steel is commonly cut into springs, automotive suspension links, and heavy‑duty machinery parts, making it a frequent choice for automotive, aerospace and equipment manufacturers. Trade terms such as FOB or CIF can be arranged, and payment methods including L/C or T/T are accepted, though exact MOQ and lead time must be confirmed directly with the supplier. Prospective buyers should request a mill test certificate and, if required, a third‑party inspection report before shipment.
