Q620D High Strength Steel Sheet

Q620D High Strength Steel Sheet

---

Q620D is a low alloy high-strength structural steel plate, often used in the machinery manufacturing industry, such as: heavy machinery, engineering machinery, chemical machinery, nuclear power equipment, bridge equipment, harbor machinery, crane equipment, ship equipment, mining machinery and equipment, etc. Q620D is also relatively widely used.

Q620D steel plate default modulation state delivery, according to the demand of different can also do hot rolled state delivery;

 

Q620D thickness flaw detection can be done: GB1 probe, GB2 probe, GB3 probe, NB1 probe, NB2 probe, NB3 probe;

 

Q620D thickness extension can be done: Z15, Z25, Z35.

 

 

Q620D steel plate grades in the Q=yield;

 

Q620D steel plate grades in the 620 = steel yield strength, unit 620Mpa indicates that the steel plate can withstand 620MPa within the yield pressure values;

 

Q620D steel plate grade in the D = steel plate level D = -20 ° C;

 

Q620D material there are 3 grades show the following:

Q620C = 0 ℃ impact, Q620D = -20 ℃ impact, Q620E = -40 ℃ impact.

 

 

Q620D is a low alloy high-strength structural steel plate, often used in the machinery manufacturing industry is more such as: heavy machinery, engineering machinery, chemical machinery, nuclear power equipment, bridge equipment, harbor machinery, crane equipment, ship equipment, mining machinery and equipment Q620D application is also relatively wide.
