Product Description:

Corresponding Steel Grade for Reference:











Chemical Composition:



















Mechanical Properties:

-Tensile Strength σb (MPa): ≥1274 (130)

-Yield Strength σs (MPa): ≥1127 (115)

-Elongation δ5 (%):≥10

-Percentage reduction of area: ψ (%): ≥40


1, Hot rolled, ≤321HB

2, Cold drawn + Heat treatment: ≤321HB

-Norm of heat treatment:

1, Quenching: 850℃±20℃.

2, Cooled by oil.

3, Tempering: 500℃±50℃.


Mechanical Properties are good. 50CrVA have high hardenability. The element V reduces thermal sensitivity and improves the strength and toughness. The fatigue strength and yield point are high but the weld ability is bad.

-50CrVA is a nice material of spring. Usually it’s used as valve spring, piston spring and secure valve spring with big section that can bear much load. The working temperature is below 300

Q:Steel industry, strip 195, where can strip be used?
195, material, steel pipe and profiles, I do not know which you ask. Roughly the same as Q235. The curve is different when it is round. There are 195 materials drilling is not convenient, carbon content is too high, easy to hurt the drill bit.
Q:Why is strip heat cheap?
Mainly the production process is not the same.
Q:What is the difference between steel strip and strip steel?
In some less strict people, it is easy to confuse these two names, but also on the Internet with the same strip of steel.
Q:What does "strip 50" mean?
It is a kind of narrow and long steel plate produced by all kinds of steel rolling mills in order to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll.
Q:What's the difference between strip 235 and 235b?
235B only requires a temperature environment of 20 degrees C; this is because of their chemical composition of sulfur, S, phosphorus, P content indicators caused by different.The 235 is 235A, 235 in the material according to the sulfur phosphorus content from high to low is divided into ABCD four grades, grade a sulfur phosphorus was the highest relative performance (welding, plasticity) is the worst, D performance is the highest, the lowest content of parathion.
Q:What about the strip scraping in the annealing furnace?
When the plate shape is not good, the strip tension is too low or the nozzle is too close to the strip, it may cause the contact between the nozzle and the strip,
Q:What are the high speed steel strips and material specifications?
(1) main usesUsed for stamping machine parts, metal products and manufacturing structural parts, etc..(2) the grade and chemical composition of the materialIn line with GB699 (high-quality carbon structural steel technical conditions), the brand is 15-70# steel provisions.
Q:Can cold rolled strip be plated with white zinc?
Sure。 Electroplating cold rolled plate surface is gray rust, after plating the cold rolling plate smoothness is higher than that of hot rolled plate.
Q:How to distinguish cold strip steel and cold rolled silicon steel sheet by simple and practical methods
If it is 0.5, you can see the coating, the silicon steel sheet is coated, cold rolling is not.
Q:Specification and use of cold rolled strip
Cold rolled strip specifications: cold rolled strip and sheet, the general thickness of 0.1 ~ 3mm, width of 100 ~ 2000mm; are hot rolled strip or steel plate as raw material, at room temperature by cold rolling rolling. Grades are generally: SPCC, Q195, Q235-B.
