Product Details

Carbon structural steel

Grade: Example Q235-A·F, which means σs=235MPa.

    Features: low price, excellent process performance (such as weldability and cold formability).

Application: general engineering structure and general mechanical parts. For example, Q235 can make bolts, nuts, pins, hooks and less important mechanical parts, as well as rebar, section steel, steel bars in building structures.

High-quality carbon structural steel

Grades: Example 45, 65Mn, 08F.

Application: Non-alloy steel used to manufacture important mechanical parts is generally used after heat treatment.

Common steel grades and uses:

08F, carbon has low mass fraction, good plasticity and low strength, used for stamping parts such as automobile and instrument housing;

20. Good plasticity and weldability, used for parts with low strength requirements and carburized parts, such as hoods, welded containers, small shafts, nuts, washers, carburized gears, etc.;

45, 40Mn, after quenching and tempering, the comprehensive mechanical properties are good, and it is used for mechanical parts with greater force, such as gears, connecting rods, machine tool spindles, etc.;

60, 65Mn steel has high strength; it is used to manufacture various springs, locomotive wheel flanges, and low-speed wheels.

Carbon tool steel

Grade: For example, T12 steel means carbon tool steel with Wc=1.2%.

Features: It belongs to eutectoid steel and hypereutectoid steel, with high strength, hardness and good wear resistance. It is suitable for manufacturing various low-speed cutting tools.

Common steel grades and uses:

T7, T8: To produce parts that withstand certain impacts and require toughness. Such as sledgehammers, punches, chisels, woodworking tools, scissors.

T9, T10, T11: manufacture tools that require high hardness and high wear resistance with less impact. Such as taps, small drills, dies, hand saw blades.

T12, T13: Make tools that are not impact-resistant. Such as files, scrapers, razors, measuring tools.

Cast steel

Grade: For example, ZG200-400, which means cast steel with σs=200MPa and σb=400MPa.

Performance: The casting performance is worse than cast iron, but the mechanical properties are better than cast iron.

Application: It is mainly used to manufacture more important mechanical parts that have complex shapes and high mechanical performance requirements, but are difficult to form by forging and other methods, such as automobile gearbox shells, rolling stock couplers and couplings, etc.

The applications of carbon steel plates include manufacturing and construction. The use of carbon steel even extends to durable storage containers that can be used for decades in the manufacturing environment, bridges, ships, and even various types of commercial and municipal buildings. The strength provided by steel, steel plate can be used to manufacture various supports and brackets, which are part of the overall structural design.



Our after-sale Service

Our Product Services

Cut large coils into small coils or Strip.
For steel coils, we can cut one large steel coil into small steel coils for loading at seaport; because for container shipping, each container usually loads weight can not be over 26 tons, but each large coil is usually about 28 tons, so one large coils has to be cut into small coils, and because the forklift usually takes 7-10 tons at seaport, so for easy loading into conatiner, each large steel coil usually is cut into 3 small coils. For bulk vessel shipping, it usually demands coils weight under 18 tons, so most times, also need cut one large coil into 2 small coils.
Open flat coils into steel plate.
For final application, need open flat the coils and cut the coils into steel plate, so we open flat the coils and cut the coils to steel plate to the sizes as required. For saving cost for loading by container, load into 20 feet containers, so cut the length under 5800mm, usually as required to cut to length 2440mm and 5800mm, width usually be 1220mm and 1500mm.after cutting the steel coils into steel plate, we can do black paints on the surface of the plate to make the plate to be anti-rust.
