50X6mm 52X7mm DIN2391 St52 NBK Precision Seamless Tube
Autmotive Precision Seamless Steel Tubes for Drag Link
Regular Size:
36*3.7mm / 40*5.7mm / 42*6.7mm / 48*5mm / 50*6mm / 52*7mm ......
Material: St52 (DIN2391), E355 (EN10305-1) Delivery Condition: NBK(DIN2391), +N(EN10305-1) Normalized(NBK/+N): The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere. With such heat treatment: Tube surface can be free of oxide scale, bright and clean. Production Process: Cold Drawn + Heat Treatment ( NBK / +N) We control stable tube mechanical property, Especially stable Yield Strength ≥ 355 MPA. Tube after necking or bending, None of crack, scratch or other surface problems.
Quality Control:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing or Cold Rolling, On line inspection
5. Heat Treatment:+SR, +A, +N
6. Straightening/Cutting to specified length/Finished Measuring Inspection
7. Quality Testing in own lab with Tensile Strength, Yield Strength, Elongation, Hardness, Straightness, etc.
8. Packing and Stocking.
