Factory Free sample High Frequency Welded Pipe - Ductile iron pipe Made in China K9 C30 C40 En545 ISO2531 – Lu
Introduction The essence of cast iron steel pipe is ductile iron pipe. Because Ductile iron pipe has the essence of iron and the performance of steel, it is called this way. The graphite in the ductile iron pipe is in the form of spheroids, and the size of the graphite is generally 6-7. In terms of quality, the spheroidization grade of the cast iron pipe is controlled to be 1-3, and the spheroidization rate is ≥80%, so the mechanical properties of the material itself have been better improved... -
Low price for Spangle Galvanized Coil - Cold rolled sheet Metal Sheet Q235 DC01 DX51D Q345 SS355JR – Lu
Introduction Cold rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also called cold-rolled sheet, cold-rolled sheet is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Because rolling at room temperature does not produce scale, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and proce... -
OEM/ODM China Galvalume Steel Coil - Hot rolled steel coil SS400 Q235 Dip Galvanized Steel Coil – Lu
Introduction Hot-rolled coils are made of slabs (mainly continuous casting billets) as raw materials. After heating, they are made into strip steel by the rough rolling mill and the finishing mill. The hot steel strip from the last rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and then coiled into a steel strip coil by a coiler, and the cooled steel strip coil. Parameter Item Hot rolled steel coil Standard ASTM, DIN, ISO, EN, JIS, GB, etc. Material ... -
Factory Cheap Hot Silicon Steel Coil - Spring steel plate Carbon structure Polished blue spring steel strip – Lu
Introduction As a general-purpose steel, spring steel is used to make springs for automobile and industrial suspensions. Generally, low-alloy manganese and medium/high carbon steels with very high yield strength are used. This allows objects made of spring steel to be prominent In the case of deflection or distortion, it returns to its original shape. For springs subjected to fatigue loads, high requirements are placed on surface finish and internal cleanliness (limiting the number of non-met... -
