2.Carbon Steel escription

Carbon steel is composed of iron and 0.12 – 2.00 percent carbon. The broader definition includes alloy

steels, which can also contain up to 10.5 percent alloy content. Even within the confines of under two

percentage points of carbon, there is huge variance in physical characteristics—especially hardness.

When people talk about carbon steel, they are usually referring to the high carbon steel used in knives and

tools. High carbon steels are very hard, which makes them good at resisting abrasion and retaining shape.

They can withstand significant force before deforming. Unfortunately, hard metals are also brittle: when

placed under extreme tensile stress, high carbon steels are more likely to crack than bend.

Low carbon steels are more common than high carbon because of (1) lower production costs, (2) greater

ductility, and (3) ease of use in manufacturing. Low carbon steels tend to deform under stress instead of b

reaking, and that ductility makes low carbon steels easy to machine and weld. They are frequently used in

automobile body panels, bolts, fixtures, seamless tubes, and steel plate.

3.Carbon Steel WN Flange Packaging

Carbon Steel WN Flanges are widely used in various industries including petrochemical, oil and gas,

power generation, bulk liquid transportation, chemicals, pharmaceuticals, pulp and paper manufacturing,

textiles and others. All our carbon Steel WN Flanges are manufactured in accordance with

international standards. carbon Steel WN Flanges are packaged to ensure that there is no

damage during transit. In case of exports, standard export packaging is done in wooden cases.
