What is the difference between hardness of 16mo3 steel and mild steel?

Based on the main hardness of 16mo3 business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel hardness of 16mo3 products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of hardness of 16mo3 pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.

The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes hardness of 16mo3 plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.

The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of hardness of 16mo3, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.

The difference of chemical composition between hardness of 16mo3, Q420D steel and Q460D steel:
Chemical composition of Q420D steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20, Al ≥ 0.015. Chemical composition of Q460D steel: C ≤ 0.20, Si ≤ 0.60, Mn ≤ 1.80, P ≤ 0.030, S ≤ 0.025, Nb ≤ 0.11, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.55, N ≤ 0.015, Mo ≤ 0.20, B ≤ 0.004, Al ≥ 0.015.
The difference of mechanical properties between hardness of 16mo3, Q420D steel and Q460D steel:
The mechanical properties of Q420D steel: yield strength ≥ 420 MPa, tensile strength 500-680 MPa. The mechanical properties of Q460D steel: yield strength ≥ 460 MPa, tensile strength 500-720 MPa.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled hardness of 16mo3 plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive hardness of 16mo3 industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
