With many years of industry experience and mature technology, the company's products are exported to more than 50 countries and regions including Europe, America, Southeast Asia, and the Middle East. Its production line covers a variety of stainless steel tubes, including ferritic stainless steel tubes. This article will introduce the basic concepts, manufacturing processes, material properties and market applications of ferritic stainless steel tubes to help readers better understand this important steel category.

What is ferritic stainless steel tube?

Ferritic stainless steel tube is a stainless steel tube with ferrite as the main microstructure. Compared with austenitic stainless steel tubes and martensitic stainless steel tubes, ferritic stainless steel tubes have a lower carbon content and a moderate chromium content, generally around 10.5% to 30%. The organization of ferritic stainless steel is a body-centered cubic structure, which determines that it has certain advantages in corrosion resistance, oxidation resistance and stress corrosion cracking resistance.

Jiangsu Jend Tube Co., Ltd. mainly produces ferrite series including TP405 (1Cr13Al), TP430 (1Cr17), TP444 (0Cr18Mo2), TP439, TP409 (0Cr11Ti), etc. These steels are suitable for different industrial fields to meet the diverse needs of customers.

Manufacturing process introduction

The production process of ferritic stainless steel tubes usually includes smelting, casting, hot rolling, cold working, heat treatment and surface treatment. Jiangsu Jend Tube Co., Ltd. implements strict quality management in each link.

Melting and casting: using advanced electric furnace smelting technology to ensure uniform and pure molten steel composition.

Hot rolling and cold rolling: by controlling the rolling temperature and speed, adjust the size and mechanical properties of the steel tube to meet the design requirements.

Heat treatment: for different uses, select appropriate solution treatment and annealing processes to ensure the stability of the internal structure of the material.

Surface treatment: In order to improve the corrosion resistance and aesthetics of the tube, pickling, passivation and other processes are usually carried out.

These processes ensure that ferritic stainless steel tubes have stable physical and chemical properties and can adapt to various complex working conditions.

Performance characteristics of ferritic stainless steel tubes

Due to their organizational structure, ferritic stainless steel tubes show the following characteristics in practical applications:

Stress corrosion cracking resistance: Ferritic steel has good resistance to stress corrosion cracking and is suitable for use in certain corrosive environments.

High temperature resistance: Some ferritic steel grades, such as TP444, contain higher chromium and molybdenum elements and can withstand oxidizing environments at higher temperatures.

Thermal conductivity and thermal expansion coefficient: Ferritic steel has a lower thermal expansion coefficient and better thermal conductivity, which is an advantage for some heat exchange equipment.

Plasticity and toughness: Although the plasticity and toughness of ferritic stainless steel are usually not as good as those of austenitic steel, it can still maintain relatively stable mechanical properties in the medium temperature range.

These properties make ferritic stainless steel tubes competitive in the industrial field.

Application fields and market demand

Ferritic stainless steel tubes are widely used in industries such as chemical industry, petroleum, boiler manufacturing, automobile industry, architectural decoration and home appliance manufacturing. For example, TP405 steel is often used in automobile exhaust systems, while TP444 is suitable for high-temperature flue gas tubes and heat exchangers. Jiangsu Jend Tube Co., Ltd. provides diversified specifications and material options to meet the needs of different customers and meet the application of multiple industries and scenarios.

With the increasing requirements of industrial equipment for material performance and durability, the market demand for ferritic stainless steel tubes has gradually increased. Especially in the context of increasingly prominent demand for high temperature resistance and corrosion resistance, the application prospects of ferritic stainless steel tubes continue to be promising.

Raw material entry inspection

Strictly review the qualifications of suppliers, use imported or high-standard billets, and rationalize inspections to ensure that the raw materials meet production requirements.

Process quality monitoring

Quality inspection points are set up in each link from smelting to forming, and non-destructive testing (NDT) technologies such as ultrasonic flaw detection and radiographic testing are used to ensure that there are no internal defects.

Final inspection and packaging standards

After the product is completed, the size, surface state and mechanical properties are systematically tested. After passing the test, protective packaging is used to ensure that it is not damaged during transportation.

Traceability management system

Through the numbering system, the production data of each batch of products can be traced, which is convenient for customers and enterprises to respond to quality issues in a timely manner.

This system ensures that every step of ferritic stainless steel tubes from raw materials to delivery is effectively supervised.
