Heat treatment of spring steel
Spring steel can be divided into hot forming spring and cold forming spring according to the different forming ways. Heat treatment of thermoforming springs. Thermoforming springs are used to make springs of large or complex shapes. Generally, quenching heating is combined with forming. That is, ...Read more -
Properties of bearing steel
Based on the working environment and damage analysis of bearing steel, bearing steel needs to have the following properties: 1. High contact fatigue strength and compressive strength; 2. Bearing steel must have high and uniform hardness after heat treatment (general bearing steel hardness require...Read more -
Advantages of ductile iron pipes
Ductile iron pipes are of much better quality than ordinary cast iron pipes. The graphite in ordinary cast iron is in sheets and has very low strength. So ordinary cast iron strength is relatively low, brittle. The graphite in the graphite cast iron is spherical, equivalent to the existence of ma...Read more -
Specific performance of the advantages of ductile iron pipe fittings
To say that the advantages of ductile iron pipe fittings are specific in what aspects, then we can first of all be sure to be the strength of the product, and there are facts and data strongly proved. According to experiments, the tensile strength of nodular cast iron is 60k, while that of ordina...Read more -

Now it is also being used in solar power production and manufacturing. Howeve...Read more -
The advantage and application of seamless steel tube
High precision cold drawn seamless steel tube is a new type of seamless steel pipe, its main characteristic is high precision. Usually there are two production processes of two-high rolling mill and three-high rolling mill. The precision of cold-rolled seamless steel pipe produced by three-high r...Read more -
Distinction between hot rolled steel plate and cold rolled steel plate
It can be distinguished by its carbon content, which is slightly higher in hot rolled steel plate than in cold-rolled steel. The density is the same if the components are not very consistent. But if the composition is very different, such as stainless steel, whether cold rolled, hot rolled steel ...Read more -
Surface problems in seamless steel tube production
Pitting and pits are common surface quality problems in seamless steel tube manufacturing. For pitting and pits in delivery, if this happens, many manufacturers will say that it is due to the quality problems of the initial round steel plant that lead to the generation of this problem. The select...Read more -
