Description of S235JR:
S235JR is the European standard non-alloy structural steel, equivalent to the NATIONAL standard Q235B, that is, carbon structural steel with low carbon content, used for welding, bolt connection, riveting structure more.
Ordinary grade surface (FA) :
Pickling surface surface is allowed to have a depth (or height) not more than half of the tolerance of the thickness of the steel plate pitting, concave, scratches and other minor, local defects, but should ensure that the steel plate and steel belt to allow the minimum thickness.
Higher Surface (FB) :
Pickling surface is allowed to have local defects that do not affect the formability, such as slight scratches, slight indentation, slight pitting, slight roller printing and color difference.
Material usage
Mainly used in building, bridge, ship, vehicle structure parts, manufacturing all kinds of tools, cutting tools, molds and measuring tools, e
Description of Q235A:
Common carbon structural steel - plain plate is a kind of steel material.
Q represents the yield of this material, and 235 is the yield value of this material, which is around 235. And the yield value will decrease with the increase of material thickness.
Because the carbon content is moderate, the comprehensive performance is better, the strength, plasticity and welding performance is better match, the most widely used.
Often rolled into rod or round steel, square steel, flat steel, Angle steel, I-beam, channel steel, window frame steel and other sections, thick steel plate.
A large number of buildings and engineering structures.
It is used for making steel bars or building workshop frames, high voltage transmission towers, Bridges, vehicles, POTS and stoves, containers, ships, etc. It is also widely used for mechanical parts with low performance requirements.
Grade C and D steel can also be used for some special steels.
