How to distinguish between hot-dip galvanized square tube and cold galvanized square tube: galvanized square tube is divided into hot-dip galvanized square tube and cold galvanized square tube in terms of consumption technology. It is precisely because the addition of these two galvanized square tubes is different that they have many different physical and chemical properties. Generally speaking, they are different in strength, toughness and mechanical properties. The square tube manufacturer will take you to understand. Hot dip galvanized square

The influence of temperature and time on the performance of square tube: at the same time, the heating temperature and time will also have a great impact on the performance of square tube. During the operation of circular furnace, the technical regulations should be strictly followed. The influence of temperature and time on the performance of square tube should be checked frequently. The billet of square tube will be burned and decarburized, In order to ensure the stability of piercing performance and chemical properties of square tube billets

Mechanical properties of square tubes 1. Performance index analysis of square tubes - plastic plasticity refers to the ability of metal materials to estimate the specifications and characteristics of efficiency enhancing square tubes under load, and introduce the specifications and characteristics of welded circular tubes and square tubes to produce plastic deformation (permanent deformation) without damage. 2. Performance index analysis of square tube - hardness and hardness are indicators to weigh the hardness and softness of metal materials. at present

Classification of seamless square tube: 1. Hardness is the pointer to weigh the soft and hard level of metal materials. At present, the indentation hardness method is commonly used to measure the hardness in consumption. It uses the indenter with corresponding geometric shape to press into the surface of the metal data to be tested under the corresponding load, and measures the hardness value according to the indentation level. Common methods include Brinell hardness (HB) and Rockwell hardness (HRA
