What are the specifications for SMA490CW shipping container steel?

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel SMA490CW shipping container steel products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our SMA490CW shipping container steel business. We also provide third-party inspection and approval services and inventory management for our customers.

SMA490CW shipping container steel, 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the SMA490CW shipping container steel and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

The steel such as SMA490CW shipping container steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.
