Cast iron 25kg weight (M1 grade method code for pig iron)How to buy and sell:

Firstly, from the perspective of appearance, regardless of the level, the minimum standard is that the surface of the weight should be flat and smooth, and it should also have good polishing. In order to prevent its interior from being corroded, it is better to choose cast iron weights with coating, and the coating must have strong impact resistance, so that there will be no bubbles, cracks, or delamination; Another very important point is that the density distribution of the weights should be uniform, and the weight of the weights should be sufficient without any shortage of weight.

Ladle iron weights are special weights made by our factory in front of open hearth, electric furnace or converter to receive molten steel and carry out pouring operations. The surface of the weights may have appropriate metal coatings or coatings for corrosion prevention. Common specifications include 2000kg, 1000kg, 500kg, 200kg, 100kg, 50kg, 20kg, 10kg, 5kg, 2kg, 1kg. Weights made from cast iron through casting process are relatively inexpensive, commonly available in flat square and lock shapes, with grades M1 and M2. As a type of cast iron weight, they have high sensitivity

Standard weights can be weighed and calibrated, and are often used in various fields such as scientific research, medicine, and machinery. The accuracy of weights directly affects the accuracy of weighing. M1 grade standard weights are commonly used in China, but some projects may require the use of F2 grade weights as the accuracy of M1 grade weights exceeds the error range. Next, let's understand the difference between the accuracy of M1 grade weights and F2 grade weights.

I believe those who frequently use standard weights are aware that weights are divided into 9 levels, and detailed levels will not be listed one by one. Among them, F2 level weights are higher than M1 level weights, and in terms of weight accuracy, F2 level weights are higher than M1 level weights.

Firstly, the materials used between the two are different. M1 grade standard weights are one of the commonly used weights with grade *, and there are also many types of materials, such as cast iron weights, brass weights, chrome plated weights, stainless steel weights, etc. However, F2 grade weights only have stainless steel as the only material, and other materials cannot meet the accuracy requirements of this grade.

Secondly, there is a difference in the error values between the two. Taking a 1mg stainless steel weight as an example, the error value of M1 grade standard weight is ± 0.20mg, and the error value of F2 grade weight is ± 0.06mg. The higher the grade, the higher the accuracy of the weight, and the error value is the main criterion for distinguishing the grade of standard weight.

Of course, for laboratories, pharmaceutical factories, and other facilities that require the use of scales, the accuracy of M1 and F2 standard weights cannot meet the work requirements. Often, F1 or higher standard weights are required, which are more precise in weighing and have a true value, also known as a correction value, that can measure the mass of objects.
