Description
Specification

NINGBO WEISHI use multiple high-performance special materials for custom valve components:

SS316L : Excellent corrosion resistance, acid and alkali resistance, widely used for marine, chemical and sanitary valve parts.

17-4PH (17-4) : High strength, high hardness and good mechanical properties after aging heat treatment, ideal for high-pressure valve stems and core components.

D2 Tool Steel: Super high hardness and wear resistance, suitable for wear-resistant valve disc and valve base under severe working conditions.

We provide full-process supporting services for custom valve parts:

1. Precision CNC Machining: Turning, milling, drilling, tight tolerance machining to ensure high dimensional accuracy.

2. Professional Heat Treatment: Hardening, tempering, solution treatment, aging treatment, improving material hardness and toughness.

3. Surface Treatment: Polishing, passivation, sandblasting, anti-rust treatment, improving surface finish and corrosion resistance.
