Why is there a big difference in the price of stainless steel pipe?
The difference in the price of stainless steel pipes is mainly caused by the following factors:1. Different materials:Stainless steel pipes are made of different materials.

Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance.
Electroplating is further divided into specific processes such as copper plating, gold plating, silver plating, chrome plating, nickel plating and galvanizing. In the field of manufacturing, especially galvanizing, nickel plating and chrome plating are the most widely used. Here’s a quick rundown of the differences between the three:
1: Chromium plating is mainly to improve surface hardness, appearance and rust prevention. Chromium plating has good chemical stability, and it does not act in alkali, sulfide, nitric acid and most organic acids, but it can dissolve in hydrohalic acid (such as hydrochloric acid) and hot sulfuric acid. Because chrome does not change color, it can maintain its reflective ability for a long time when used, which is better than silver and nickel. The process is generally electroplating.
2: Nickel plating is mainly wear-resistant, anti-corrosion, anti-rust, generally thinner, and the process is divided into two types: electroplating and chemical.
3: Galvanized is mainly beautiful and anti-rust. Zn is an active metal that can react with acid, so it has poor corrosion resistance and is the cheapest of the three.
The difference in cost is that chrome plating is the most expensive, followed by nickel, and zinc is the cheapest. Among them, rack plating, barrel plating, etc. must be distinguished. Rack plating is expensive, barrel plating is cheap.

This week, the pressure on supply and demand in China’s domestic steel market has increased, and demand continued to be weak,
The current situation of China’s domestic steel market this week: Due to the increasing downward pressure on the domestic economy and
This week, China’s domestic high temperature, and affected by the off-season of the steel market, the demand for steel has shrunk,
This week, the output of China’s five major types of steel was 8.9713 million tons, an increase of 140,300 tons from
