Our company supply various size and thickness S460M specification, hot rolled plates. Plate thickness is available ranging 3mm to 350mm. Steel coils thickness are supplied in max. 25mm. Tolerances for carbon steel coils for conversion to: For minimum gauge orders, thickness and width tolerances are in accordance with the respective ASTM specifications of A568 for thicknesses of less than 0.230 inches(exclusive), and A635 for thicknesses of 0.230 inches to 1.00 inch, inclusive.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S460M specification etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S460M specification etc. steel is strictly controlled.

Tempering the important S460M specification welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve S460M specification strength, plasticity and toughness.

From the perspective of market conditions, today S460M specification spot prices are operating smoothly, futures are volatile, and market acceptance is average. Merchants have a wait-and-see attitude. Low-price transactions are average, while high-price transactions are poor. Most merchants have daily transactions of 200-300 tons. between.
