30 CrMnti alloy round steel main use explanation

More than 20 CrMnti intensity, high hardenability, but slightly lower impact toughness. Mainly used for carburizing steel, can be temperature and direct quenching after carburizing and high bending strength, wear-resisting performance is good. Can be used after quenching temperature tempering or conditioning, cutting machining medium. Used in the manufacture of tractor industry in the cross section of the larger heavy-duty carburizing and force of the larger gear, gear shaft, worm, etc.

Introduction to the characteristics of steel with good performance

It is mainly used for large-area wear conditions. It has good performance in terms of toughness and plasticity. The use of surfacing technology can increase the thickness and hardness of the product, because it uniformly welds the high-hardness self-protected alloy wire during welding. on the substrate. The number of composite layers is from one layer to two layers or even multiple layers. During the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear. It has its presence in metallurgy, coal, cement, electricity, glass, mining, building materials, brick and other industries.

What is the difference between I-beam and H-beam?

People often ask that I-beam and H-beam are similar in shape, how to choose in practical application? Many people who have been in the construction industry for many years cannot explain it in detail. Here is a detailed answer for everyone: Many people think that Chengdu I-beam is the domestic name, and H-beam is the foreign name. In fact, this perception is wrong. H-beam and I-beam are different in shape!

Construction measures of I-beam

The example project is a high-rise residential building with 18 floors above ground and 2 floors underground. Residential toilets use settlement boxes with a height of 300mm around and a waterproof sill with a thickness of 100mm.
