5. Characteristic of 1.2311 steel flat bar:
1. Vacuum degassing refining processing steel purity, suitable for polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need in heat ttreatment can be directly used for mould processing, shorten the construction.
3. After heat treatment machining and polishing performance is good, the nitriding treatment, can be suitable for chrome plating surface treatment, such as material is qualitative hardness is uniform (400mm thick), good toughness and good machining performance.

Our company have introduced large-sized vertical saw machines, horizontal saw machines, milling machines, grinding machines and other advance equipments, we can export our products by wholesales and retail sales, whole plate or strip is available. All our products can meet the standards of DIN, AISI, JIS and GB, all the material should be inspected the ultrasonic, hardness and others strict inspection process before the shipment!

We can provide below service:
A. Steel plates: Cutting by bandsaw machine, milling, heat treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and turned, heat treatment, etc
