Mechanical properties of SM490B steel plate

(1) d is the diameter of the bending center and a is the thickness of the sample.

(2) The impact test is calculated according to the average value of three samples in a group. The single value of one sample of SM490B steel plate is allowed to be lower than the specified value, but not lower than 70% of the specified value.

Note: Trace alloying elements can be added if necessary

a. The company's main steel plate varieties: boiler and pressure vessel plate, low alloy plate and high strength plate, bridge plate, alloy plate, carbon steel, wear-resistant plate, pipeline steel, nuclear power steel, wind power steel, ship plate, building structure steel, die steel, military steel plate, hydrogen plate and various special steel, etc.

b, according to the demand for SM490B steel plate processing, cutting a variety of special-shaped parts, and transport agents, short delivery cycle.

c, for SM490B steel plate additional detection requirements and Z-direction performance (Z15/Z25/Z35), SM490B steel plate can be hot rolled, controlled rolling, normalizing, annealing, normalizing + tempering, tempering.
