Cause of corrosion pits on EN steel grade S460ML material

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the EN steel grade S460ML material industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the EN steel grade S460ML material industry with scientific management, high quality, first-class service and harmonious development

A36 steel plate contains different amounts of other materials such as carbon, nickel, manganese, tungsten and molybdenum. Different components in EN steel grade S460ML material A36 steel plate will produce different properties. The modulus of elasticity (i.e. hardness measurement) of all A36 plates is 29 million psi.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. EN steel grade S460ML material, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled EN steel grade S460ML material plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy EN steel grade S460ML material steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.

As for Q460 series low alloy steel, there are three quality Grade C, D, E. EN steel grade S460ML material, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
