What is MS square tube?
MS square tube, also known as mild steel square tube, is a hollow structural profile (HSS) made of mild steel. It is a square metal tube commonly used in construction, engineering and various industrial applications. It is characterized by high strength, light weight, good corrosion resistance, easy processing, weldability, etc. In the construction and manufacturing world, it is crucial to understand the material grade of MS square tubes. These versatile components are widely used in various industries due to their structural integrity and durability. Below, PMC delves into the intricate details of the MS square tube material grade, elucidating its composition, properties and diverse applications.
Square tube material:
Square tubes are made of a wide variety of materials, and common materials include carbon steel, alloy steel, stainless steel, etc. Among them, carbon steel is the most commonly used material. According to different carbon content, it can be divided into ordinary carbon structural steel and high-quality carbon structural steel. Low carbon steel (mild steel) is an ordinary carbon structural steel with a carbon content generally between 0.05% and 0.25%. Square tubes can be divided into two types: seamless square tubes and welded square tubes according to the production process. According to different cross-sectional shapes, they can be divided into rectangular tubes and square tubes.
Characteristics of mild steel:
Mild steel usually refers to carbon steel with a carbon content of less than 0.25%. It is also called mild steel because of its low strength, low hardness and softness. It includes most ordinary carbon structural steel and some high-quality carbon structural steel. Most of them are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatments.
The annealed structure of low carbon steel is ferrite and a small amount of pearlite, which has lower strength and hardness and better plasticity and toughness. Therefore, it has good cold formability and can be cold formed by curling, bending, stamping and other methods. In addition, this steel has good weldability.
MS square tube material grade classification:
Material grades of MS square tubes are typically classified based on their chemical composition and mechanical properties. The two main grades are ASTM A36 and ASTM A572.
ASTM A36: This grade has a minimum yield strength of 36,000 psi and offers excellent formability. It is typically used in structural applications where precision engineering is not a priority.
ASTM A572: This grade has a minimum yield strength of 50,000 psi and is known for its higher strength compared to A36. It finds its place in more demanding applications, such as heavily loaded bearing structures.
Mechanical properties:
MS square tubes exhibit excellent mechanical properties, making them suitable for a wide range of applications. These properties include:
1. Tensile strength: The ability to withstand tensile force without deforming or breaking.
2. Yield Strength: The point at which a material begins to deform under applied stress.
3. Elongation: The percentage increase in length of a material when it is subjected to tension.
4. Modulus of elasticity: Reflects the ability of a material to elastically deform under pressure and return to its original shape after release.
Advantages of using MS square tube:
1. Material: MS square tube is made of mild steel, a type of mild steel known for its durability and strength and popular in various industries.
2. Shape: As the name suggests, MS square tube has a square cross-section. They are available in various sizes and thicknesses to meet different requirements.

4. Corrosion resistance: Although it is not completely immune to corrosion, proper coating and maintenance can significantly extend its service life.
5. Low cost: Compared with other steel materials, mild steel is relatively cheap and easy to obtain, making it a budget-friendly option for a variety of projects, and its lower carbon content can also reduce environmental pollution.
6. Weldable: Mild steel is easy to weld, allowing the use of MS square tubes to manufacture various structures and frames, achieving seamless connections and strong joints
7. Mechanical properties: It has good plasticity and toughness, can be manufactured into various shapes, and has high strength and hardness.
8. Versatility: MS square tubes are widely used in construction, infrastructure, automobiles and even furniture manufacturing due to their adaptability.
Maintenance and corrosion protection:
While MS square pipe offers multiple advantages, its susceptibility to corrosion must be addressed. Over time, corrosion can compromise the structural integrity of pipes. To mitigate this situation, several maintenance and protection methods can be employed:
1. Coating: Applying a protective coating such as paint, zinc or epoxy can effectively protect pipes from moisture and corrosive elements. Regular inspection and re-applying of coatings is necessary to ensure continued protection.
2. Galvanized: Galvanized MS square pipe is coated with a layer of zinc to enhance corrosion resistance. These pipes are typically used outdoors and in humid environments.
3. Maintenance Plan: It is crucial to have a maintenance plan that includes cleaning, inspections, and potential repairs. Prompt rust removal and addressing any signs of deterioration can extend the life of your pipes.
Application of MS square tube:
The application of MS square tube covers many industries:
