Veidt Weighing is a Stainless Steel Weight factory in china. Stainless steel weights are indispensable precision measuring tools in modern laboratories, industrial production, and quality testing. This standardized weight tool made of high-quality stainless steel material is widely favored for its excellent corrosion resistance, stability, and precision. Stainless steel weights are widely used in the calibration and verification process of various electronic and mechanical scales, and are the basis for ensuring accurate and reliable measurement results.

Stainless steel weights are usually made of 304 or 316 stainless steel, which have significant advantages due to their special chemical composition:

304 stainless steel: containing 18% chromium and 8% nickel, with good corrosion resistance and mechanical properties
316 stainless steel: Adding 2-3% molybdenum on top of 304 to further improve corrosion resistance, especially suitable for humid or corrosive environments

The selection of stainless steel materials ensures that the weights are not easily rusted or corroded during long-term use, and have extremely low magnetic properties, which will not interfere with precision weighing equipment. The density of this material is about 7.9g/cm ³, ensuring that the weight volume is appropriate for easy use and storage.

Stainless steel weights are divided into multiple precision grades:

E1 level: highest accuracy, used for national metrology institutes and standard transmission
E2 level: High precision, suitable for precision laboratories and standard laboratories
F1 level: Industrial grade high precision, used for routine laboratory testing
F2 level: General industrial use
M1 level: General industrial use
M2 level: General commercial use

The allowable error range for weights of different grades varies, and the higher the grade, the smaller the allowable error. The error of E1 grade weights usually does not exceed ± 0.0003%, while the error of M2 grade weights may be around ± 0.1%.

The weight specifications of stainless steel weights cover a wide range, from the smallest 1mg to the largest 50kg. Common specifications include:

Milligram group: 1mg, 2mg, 5mg, 10mg, 20mg, 50mg, 100mg, 200mg, 500mg
Gram group: 1g, 2g, 5g, 10g, 20g, 50g, 100g, 200g, 500g
Kilogram group: 1kg, 2kg, 5kg, 10kg, 20kg, 25kg, 50kg

There are various shapes of weights, designed according to different weights:

Small mass weights (≤ 50g) are usually in the form of sheets or filaments
Medium weight weights (50g-1kg) are mostly cylindrical or hexagonal in shape
Large weight weights (≥ 1kg) are often designed with a handle structure for easy handling

The production of high-quality stainless steel weights requires strict process flow:

Material selection: Choose stainless steel raw materials that meet the standards
Precision machining: using CNC machine tools for high-precision machining and forming
Surface treatment: Polishing and grinding to achieve the specified surface roughness
Demagnetization treatment: eliminating the magnetism generated during the processing
Cleaning and drying: removing surface impurities and oil stains
Quality inspection: check the size and weight one by one

Precautions for use

Use specialized tweezers or gloves for retrieval and placement, avoiding direct contact with hands
Handle with care to prevent collisions and falls
Before use, check if the surface of the weight is clean
Avoid use in corrosive environments
Regularly conduct calibration checks

Cleaning and maintenance methods

Gently wipe with a soft, lint free cloth
Stubborn stains can be cleaned by diluting them with neutral cleaning agents
Immediately dehydrate and dry with anhydrous ethanol after cleaning
Store in a dry and dust-free environment
Long term non use should be coated with anti rust oil for protection

Stainless steel weights play an important role in various industries:

Metrological verification institutions: used for the verification and calibration of various weighing equipment
Laboratory: Accurate Weighing in Scientific Research Experiments and Quality Control
Pharmaceutical industry: precise weighing of drug formulas and raw materials
Food industry: formula research and development, production process control
Electronics industry: weight detection of precision electronic components
Jewelry industry: precise weighing of precious metals and gemstones
Educational institutions: Physics and Chemistry Experiment Teaching

When choosing stainless steel weights, the following factors should be considered:

Accuracy level: Select the appropriate accuracy level according to actual needs
Material requirements: Choose 304 or 316 stainless steel according to the usage environment
Specification configuration: Select the appropriate combination of specifications based on the range and working requirements of the weighing equipment
Supporting accessories: Consider whether specialized tweezers, storage boxes, and other accessories are needed
Supplier Qualification: Choose a reputable manufacturer or authorized distributor
After sales service: Understand calibration service and warranty period

As a fundamental tool in the field of metrology, the accuracy and reliability of stainless steel weights directly affect the measurement results of various industries. Understanding the characteristics, correct use, and maintenance methods of stainless steel weights is of great significance for ensuring the accuracy of measurement data. With the continuous improvement of quality control requirements, stainless steel weights will continue to play an irreplaceable role in the field of precision measurement.
