introduction
Mild Steel A36 in CNC Machining
Mild steel A36 is a popular type of structural steel in manufacturing and machining because it is easy to work with and cost-effective.
It's commonly used in mild and hot-rolled forms due to its strength, toughness, ductility, and versatility. We can machine A36 using various processes such as milling, turning, drilling, and tapping. We adjust the cutting speeds and feeds based on the specific CNC machining operation and tooling. We use carbide tools in machining and do proper lubrication/cooling to extend tool life and improve machining efficiency. We can also perform post-machining processes like heat treatment, coating, or other surface treatments to enhance the material's properties.
We offer A36 in different types for various purposes. A36 sheet metals are used in auto bodywork and construction. A36 steel bars reinforce concrete, while plates support structures. Hot-rolled A36 is common and cost-effective. Annealed A36 undergoes heat treatment for better machinability. Cold-drawn A36, made at lower temperatures, is stronger with a refined finish, suitable for shafts and aesthetically pleasing products.

TECHNOLOGY OVERVIEW
Basic Knowledge of Mild Steel A36
What is Mild Steel A36?
A36 steel is a type of mild or low-carbon steel with a carbon content ranging from 0.25% to 0.3% and approximately 1% manganese. It's known for its strength, weldability, versatility, and malleability at a cost-effective price. A36 steel exhibits good magnetic field conductivity, rendering it relatively opaque to electromagnetism.
The production of A36 carbon steel involves melting iron ore with coal to eliminate impurities and adding alloying elements like manganese and carbon. The molten metal is then solidified into ingots and subjected to hot rolling, a process where the ingots are rolled into their final dimensions at elevated temperatures.

FAQ
Machining Mild Steel A36 Buying FAQ
A36 is a mild steel commonly used in construction and structural applications. Several steel grades are stronger than A36, such as A572 and A514. A572 is a high-strength, low-alloy steel, while A514 is a quenched and tempered alloy steel known for its high yield strength.
While A36 steel is primarily used in construction and industrial applications, it is not designed for cooking. Cooking on A36 steel may not be advisable due to the potential presence of coatings, treatments, or residues that could be harmful when exposed to high temperatures.
Yes, A36 steel can be galvanized. Galvanization involves applying a protective zinc coating to steel to prevent corrosion. A36 steel is often galvanized to enhance its corrosion resistance and increase its lifespan in outdoor or corrosive environments.
A36 steel is generally weldable using common welding processes such as MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding. Common filler materials for welding A36 include ER70S-6 for MIG welding and E7018 for stick welding.
