NM400 weight calculator plate weldability
NM 400 is a wear-resistant steel plate that provides superior performance in both abrasive and impact applications. This type of steel is known for its excellent strength and durability, making it an ideal option for various industrial applications. Despite its incredible hardness, the steel is still fairly easy to weld, allowing for a variety of different assemblies or welded joints.
The NM 400 plates are made of a low-alloy steel and are widely used in mining, transportation, agricultural and defense-related applications. They possess an incredibly good combination of hardness, strength and ductility. Additionally, due to its unique hardness, it also has abrasion resistant properties that make it particularly suited for applications exposed to high wear and tear.
When it comes to welding NM 400, one of the most important things to consider is its chemical composition. The steel is made from 0.08-0.20% Carbon, 0.70-1.60% Silicon, 1.70-2.30% Manganese, and 0.40-0.90% Chromium. The steel must also meet certain other key criteria to be suitable for welding, such as tensile strength greater than 700MPa and an elongation between 2-20%.
To ensure good weldability, it is also important to use the right type of welding method. The most popular methods for welding NM 400 include oxyacetylene welding, shielded metal arc welding, gas tungsten arc welding, and gas metal arc welding. It is also possible to braze or soldering NM 400 plates and rods.
To further ensure the success of a weld and to ensure the highest quality outcome for your application, it is important to factor in the thickness of the plate materials when selecting your welding process. The preferred minimum preheat temperature for NM 400 should be between 200 and 300 degrees Celsius. This can be adjusted according to the thickness of the material you are welding with.
The NM 400 plates have a maximum thickness of 70mm, while the rods can be up to 100mm thick. Due to the material’s intense strength and ductility, it is also possible to perform cold forming or other post-welding processes to further shape the welded parts as per your application requirements.
When preparing the materials for welding it is also important to pay close attention to the cleanliness of the surface. Applying a pre-weld cleaning procedure can help to reduce the risk of porosity and ensure that welds are strong and reliable. This can include chemical pickling, shot blasting, grinding, wire brushing, and chemical degreasing.
To determine the size and weight of plates you will be using for your application, you can use a handy NM 400 weight calculator. This helpful tool allows you to enter the dimensions of the plate and its thickness to accurately calculate its weight per square meter.
In summary, NM 400 plates and rods are an excellent choice for a variety of industrial applications ranging from mining, transportation and agricultural to defense-related uses. Thanks to its combination of excellent weldability and extreme wear resistance, NM 400 is ideal for any applications that demand reliable performance under heavy use or exceptionally harsh conditions. With the right welding methods, the right preheat temperature and good surface preparation, it is possible to get the highest quality welds with NM 400.
