S355ML angle bar specification and properties

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). S355ML angle bar, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.

Difference between Q345R boiler vessel plate and ordinary Q345 plate, S355ML angle bar:Q345R boiler vessel plate is pressure vessel steel, Q345 plate is low alloy steel.Q345R boiler vessel plate generally requires flaw detection and positive deviation, while Q345 plate generally has lower requirements.In terms of performance, Q345R boiler vessel plate and Q345 plate are of the same level. However, due to high requirements, they can not be mixed in general.Generally, the requirement of Q345R boiler vessel plate is higher than Q345 plate, S355ML angle bar.

Cold rolled S355ML angle bar steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner S355ML angle bar steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

We have a professional production team and high-quality production equipment, and we also have a great S355ML angle bar advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the S355ML angle bar production of high-quality steel plates, steel pipes and other products that meet customer requirements.

The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for S355ML angle bar iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.

The results of adopting two-level S355ML angle bar service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and S355ML angle bar after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
