Recommended Methods For Testing Stainless Steel:
1. Spectrometer Detection (more Professional);
2. Stainless Steel Potion Detection, Drop Detection Liquid On The Surface Of The Material To Observe The Color Change;
3. Wash The Steel Ball With Water And Store It In The Open Air To Observe The Surface Changes. Iron Balls, Carbon Steel Balls,
Bearing Steel Balls Will Begin To Rust The Next Day After Washing, And The 304 Stainless Steel Will Not Change.
☆ Measure The Size: Use A Standard Vernier Caliper To Measure, Measure The Outer Diameter Of The Steel Ball,
Do Not Measure With A Tape Measure And A Ruler, Which Is The Most Error-prone.

☆ Why Is The Stainless Steel Ball Magnetic?
Answer: The Magnetic Properties Of Stainless Steel Balls Are Caused By Cold Working. The Microstructure Of 304 Stainless Steel Raw Materials,
Such As Wire Rods, Wires, And Steel Wires, Is Austenite. This Structure Shows Paramagnetic Properties (weak Response To Magnetic Fields. As The
Saying Goes Without Magnetism); During The Cold Working Process Of Stainless Steel Balls (wire Drawing,Cold Forging, Light Ball, Hard Grinding),
Part Of The Austenite Structure Will Be Transformed Into MartensiticStructure, And The Steel With Martensitic Structure Is Magnetic. In General, The
Greater The Deformation Of The Material And The Lower The Temperature During The Processing, The Stronger The Magnetic Properties After Processing;
After Processing Into A Ball, The Stable Austenite Structure Will Be Restored By High Temperature Treatment, So As To Carry Out Demagnetization Treatment,
But It Cannot Be Completely Eliminated, That Is, It Will Lead To Stainless Steel. Steel Balls Weak Magnetism.
