Welcome to BBN High Strength Steels Factory

S690QL plate equivalent converter

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of S690QL plate equivalent these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the S690QL plate equivalent product workpiece, thereby improving the production efficiency and production processing quality.

Steel transportation because of the special material of S690QL plate equivalent steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the S690QL plate equivalent, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
