Alloy steel tools

Alloy steel tools

Inch insert thread gages is used to detect the pitch diameter and spacing precision of internal threads. The OHSG inch plug gages is manufactured for the X tolerance per AHNSI B1.2. Starting from OHSG, not taking gages, starting with high quality HGSS and hardening to 64Rc, to ensure superior wear resistance. Gages can be authenticated in short or long form. Use a standard EDP number and use a short-form certificate to order gages. To use gages for long format certificates, use the EDP number in LF.

Characteristics of the

Standard 2B with high quality high speed steel (HGSS) standard 2B, available from stock for 64 HrC

Excellent wear resistance, same-day delivery – no authentication delay

Flat die

The flat die produces external threads in the process of cold forming. The flat mold USES a fixed and a motion mode to form threads. OHSG death is hardened and can be treated with nitride or our own XHBT surface. OHSG provides the full service local regrinding function of OHSG and non-ohsg leveling modules.

The planets die

The planetary mould USES a fixed line segment and a circle of rotary molds to form threads. They are accurate on the surface of the rotating and linear surfaces. Precise heat treatment processes ensure that the worn life is consistent and can be treated with nitrides or our own XHBT surfaces.

Cylindrical mold

The cylindrical mould is ideal for all kinds of precision thread parts. They are made for rolling over feed. We provide full-service localized regrinding capacity for OHSG and non-ohsg cylindrical molds, and our molds can be treated with nitrides or our own XHBT surfaces.

Trimming die

In the cold head processing of bolts and fasteners, the trim mould is designed to eliminate flickering afterglow. There are many configurations for several different tool steels that are customized for your application. OHSG can quickly produce custom decorative molds and achieve the highest quality standards.
