What is difference Q415NH low alloy steel and s235

The development Q415NH low alloy steel of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with Q415NH low alloy steel high-quality and efficient services, work together for win-win, and create a better tomorrow!

In our impression, stainless steel, as the name implies, will not rust, which is why many people choose stainless steel. Stainless steel has beautiful appearance, corrosion resistance, wear resistance, high strength, so it has a certain charm. In the past few decades, Q415NH low alloy steel, stainless steel has been widely used in all aspects of industry and daily life. Under normal conditions, stainless steel will not rust. Improper use, such as long-term exposure to seafood and other salt environment, stainless steel surface will also occur corrosion.

SA516 gr.60 boiler plates are primarily intended for use by pressure vessel fabricators and manufacturers. And, physical and chemical characteristics of the boiler quality plates make these a popular choice in the industries. SA516 gr.60 boiler steel plates are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built. Also, these plates Q415NH low alloy steel are repellent to corrosion and therefore is long-lasting and can also be used in different environments for a long time without any deterioration.

The basic principle of Q415NH low alloy steel, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. Q415NH low alloy steel, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.
