What is S690QL1 specification used for

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the S690QL1 specification industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the S690QL1 specification industry with scientific management, high quality, first-class service and harmonious development

The company has strict control on the quality of S690QL1 specification. Each S690QL1 specification is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the S690QL1 specification meets the specified quality requirements. If the S690QL1 specification does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified S690QL1 specification shall be removed, marked, registered and effectively isolated; the S690QL1 specification shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. S690QL1 specification, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in S690QL1 specification steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of S690QL1 specification steel.

SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the S690QL1 specification, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.
