2 1. Applications

Large plastic moulds with deep engravings and intensive impacts on the core. Pre-hardened Plastic Mold Steel is the logical development of 1., a pre-hardened plastic mould steel for use in large moulds, which also have to display high core strength. The additional nickel content of 1 % increases through hardening. Formadur ia a micro-alloyed, vacuum-degassed steel with the following excellent features: good machinability, outstanding polishability, good texturing properties.

 

1. mold steel materials are generally used for relatively low temperature applications such as die casting dies and injection moulds, synthetic plastic moulds dies, especially for large plastic moulds higly stressed in core, hydroforming tools, such as up to 400 mm in the construction of plastic moulds. DIN 1. is suitable for nitriding and chrome plating.

DIN 1. steel is one kind of plastic mold steel, equivalent to AISI P20+Ni tool steel. While Nickel, chromium and molybdenium are the alloying elements for hardness and toughness. 1. tool steel is specially designed for plastic mold industry, especially for big steel mold parts.

DIN 1. tool steel is usually supplied as pre-hardened/quenched and tempered 280 &#; 320 HB hardness condition
With good machinability, DIN 1. steels is with better polishability compared to 1. (AISI P20+S).
Material 1. can be through nitrogenation and flame hardening treatment in order to increase the hardness and wearability of mould surface.
The steel 1. is melted in an electrical furnace and refined with VOD or DH device.

With competitive price and timely delivery, Jiebao sincerely hope to be your supplier and partner.

What is the 1. Steel Equivalent Steel Grade ?

DIN 1. steel grade is one common and popular steel grade. It is widely used as mold steel. But what is 1. steel equivalent ? Some customer don&#;t know it for sure.

It is equivalent to AISI P20+Ni in ASTM standard system. So, when you need to compare 1. steel equivalent, steel grade P20+Ni would be an alternative for sure.

Besides, some steel giant such as Bao Steel company, there is grade 718H steel grade. It&#;s also one equilvalent steel grade to 1. steel.

Otai is stable and reliable supplier for Fortune 500 companies at home and abroad, such as Bohler, Uddeholm, Schlumberger, Thyssenkrupp, China North Industries Group Corporation Limited.

For those tool steel, Otai will be your reliable choice.
