Q550B steel is a low-alloy high-strength structural steel grade. Steel Q550A is not required for impact toughness test; Q550B is for impact toughness test at room temperature (20℃); Q550C is for 0℃ impact toughness test; Q550D is for impact toughness test at -20℃; Q550E grade is for impact toughness test Make impact toughness test at -40℃. The impact toughness test uses Charpy V-notch specimens. The impact toughness index is Akv.

price of NM400 steel, Chinese material Q235B is one of the most widely used carbon steel in the world. Some like to compare its strength with other equivalent steel grades. We need to take care that the Q235B steel strength varies with thickness. For the min. yield strength of Q235B steel plate: it is 235Mpa if thickness ≤16mm, 225 Mpa for thickness 16-40mm, 215 Mpa for thickness 40-60mm, 205 Mpa for thickness 60-100mm, 195 Mpa for thickness 100-150mm, 185 Mpa for thickness over 150mm. The tensile strength of Q235B steel plate is 375-500 Mpa.

Spring steel, as we can clearly know from its name, is one of the main materials used to make springs and special alloy steel for other elastic components. price of NM400 steel, Spring steel has good comprehensive properties, it has heat resistance, low temperature resistance, oxidation resistance, corrosion resistance and so on advantages. Compared with alloy spring steel, carbon spring steel has less advantages, but its price is cheaper, and the source of raw materials is convenient. The disadvantage of carbon spring steel is that the elastic limit is low and it is easy to lose elasticity after repeated deformation.
