High Strength Steel Tubing is a special type of tube that is used for high abrasion resistance, strength and hardness. The material is a brand known as domex that is rebranded. Suryadeep Industry is a leading supplier of the High Strength Steel 700MH Tubes which are the most used of the strenx tubes. There are different grades of strenx such as the 600MC, 700, 900 and so on. The material is strong and has 700MPa minimum yield strength. The 700MLH Tube has a high tensile strength ranging from 750MPa to 950MPa. It is a hot rolled plate material that is suitable for cold working and machining. The material has high forming capacity. The High Strength Circular Steel Tubes are used in high abrasion applications with high strength such as in construction material transportation like the wet concrete mixtures.
The High Strength Square Tube is used for its geometrical strength. The tubes come from 3mm to 10mm in wall thickness and the diameter can range from 30mm to 300mm. The High Strength Rectangular Tube mill length ranges from 6000 to 12000mm or sometimes up to 18000mm. The tubes can come in circular, square and rectangular shapes. The 700 MH High Strength Steel Tube is used in heavy load bearing applications and in high power machineries that deal with high friction applications. The petroleum refineries, oil and gas industrial applications, petrochemicals and pulp and paper industries all use the 700 MLH High Strength Structural Hollow Tubes for long lasting life. The 700 QLH Tubes have titanium, vanadium, niobium, aluminum and carbon in the composition which allows them to be stronger and abrasion resistant. The heat treatment makes the material even stronger. There are different types of these tubes such as the Steel 900 MH Tube and others. We manufacture and supply them according to international standards. Please contact us for any needs in the EN 1090-2 High Strength Steel Tubes.
