The density of q235 is 7.85 g/cm 3, the letter Q indicates the yield limit, the number 235 indicates the yield value of 235MPa, and the tensile strength is about 375-460MPa (3750-4600kgf/cm2). However, the yield value will decrease with the increase of steel thickness, so everyone must pay special attention when purchasing.
What is the material of q235 steel?
This kind of steel is simply carbon structural steel. Like A3 and C3 steels in the old standard, they are all Russian TOCT brand. Q in steel grade stands for yield strength. In general, this kind of steel can be used directly without heat treatment, but it must be standardized when used, otherwise it will easily lead to problems such as cracking and damage.
What is the purpose of q235 steel?
1, this steel has moderate carbon content, good comprehensive properties, strong plasticity, good weldability and wide application. Can be made into wire rod, round steel, square steel, flat steel, I-beam, channel steel, medium-thick steel plate and other products.
This kind of steel is widely used in building engineering. In addition, it has many other uses to meet the needs of different users.
3. This kind of steel can be used to make steel bars, build factory supports, bridges, vehicles, boilers, containers, ships and so on. It can also be used as a mechanical part.
4. This steel can not only be made into handles with different abrasives, but also be used as non-weight abrasive parts.
5. This kind of steel can be used as a punch, so it can be used directly after quenching, and its hardness is between 36 and 40 hours RC, which can avoid the problem that the punch is broken when used.
The relevant content about q235 density is as above, and I hope it will be helpful after reading it.
