Welding performance of S690QL material

The X80M pipeline steel customized by the company for customers will be supplied to a construction machinery manufacturing enterprise for making core components of rotary drilling rigs. Based on the original production process of high-end S690QL material pipeline steel, the company formulated and optimized the process plan and production operation plan, strictly controlled the content of harmful elements in the production, optimized the rolling parameters and cooling mode, and ensured that all performance indexes of customized X80M S690QL material pipeline steel met the requirements of customers.

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

Stainless steel plates are alloy steels with very good strength, precision, and toughness, and can be used for many purposes in processing. The surface of the stainless steel plate is smooth and beautiful, and it can be processed into various high-end hardware products. S690QL material, Stainless steel plates have outstanding characteristics and a wide range of applications. Stainless steel plates are used outside of buildings in coastal areas to prevent corrosion. The seawater has strong acidity and alkalinity. General steel plates are prone to rust and corrosion for a long time.

BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel S690QL material, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.

With the increase of temperature, the yield limit of S690QL material will decrease monotonically, but the tensile strength of S690QL material will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S690QL material. Near the blue brittleness temperature, the S690QL material strength increases and the plasticity decreases. The elongation and section shrinkage of S690QL material increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other S690QL material steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market. Let’s work together!

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
