●No. steel pipe mechanical properties: tensile strength: yield strength: elongation Rate (%): Area shrinkage (%): Hardness: Unheated sample size: Sample size
●Heat treatment specifications and metallographic structure of steel pipe: Heat treatment specifications: Normalizing ℃ air cooling. Metallographic structure: ferrite + pearlite.
●No. steel pipe delivery status: delivered in unheated or heat treated (annealed, normalized or high temperature tempered) state. If the product is required to be delivered in a heat-treated state, it should be clearly stated in the contract. Otherwise, the product will be delivered without heat treatment.
Usage: Used to manufacture parts that require low stress and high toughness, such as automobile bodies, containers, deep-drawn vessels, pipes, gaskets, etc., which can be used for cold rolling, cold stamping, cold heading, cold bending, and hot rolling. The forming process can also be used as carburized parts and carbonitrided parts with low core strength.
High-quality carbon structural steel (-)
In addition to carbon elements and a certain amount of silicon (generally not more than .%) and manganese (generally not more than .%), high-quality steel pipes (generally not more than .% are higher) It can reach .%) and does not contain other alloying elements (except residual elements). This type of steel must ensure both chemical composition and mechanical properties. The content of sulfur and phosphorus impurity elements is generally controlled below .%. If the steel is controlled below .%, it is called high-grade high-quality steel, and a distinction should be made at the end of the brand. For example, if the steel is controlled below .%, it is called special-grade high-quality steel. The content of other residual alloying elements such as chromium, nickel (), copper, etc. brought into the steel from raw materials is generally controlled at .%, %, .%. Some brands have manganese () content reaching .%, which is called manganese steel.
