|
7, Heat Treatment We could do different heat treatment ways according to mechanical properties which customer request. |
8, Inspect Mechanical Properties We will cut a test specimen from product body to test, and continue producing after test specimen approval. |
|
|
|
9, Machining Machining according to drawing dimentions or customer's delivery dimention request. |
10, Magnetic Particle Testing (MT) We usually use MT to inspect surface cracks of products. |
|
|
|
11, Ultrasonic Testing (UT) We usually use UT to inspect the size of products internal defect, and tell approval or not according to customer's UT grade request. |
12, Final Inspection We will do visual inspection and inspect dimentions of products by measuring inplements after finishing. |
