ASTM A514 steel is mainly used in places where high tensile strength and high yield are required, such as engineering vehicle lifting gears, large excavators, offshore platforms, etc. Different grades of A514 steel plate have different thickness, chemical composition and properties. However, the S420NL material steel mechanical properties specified in ASTM A514 are similar to those of Q690 in China. A514 grade Q is generally used as the rack for offshore platform. Its hardness is between 230-390MPa, yield is greater than 630MPa, and tensile strength is more than 700MPa.
Our company will accept the product quality objection registration record, pass it to the S420NL material steel production unit and relevant departments, and timely coordinate the supervision of product S420NL material steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the S420NL material steel, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
