ST Power Hammer STH-25, 25 KG

ST Power Hammer 25 KG, STH-25

**PRE-ORDER NOW FOR NEXT BATCH WINTER 2025 ***

Anyang ST Power Hammer for forging with 25 kg ram weight for blacksmithing.

Strong cast iron frame, hardened dies in 5CrMnMo for excellent wear resistance, die face size 100 x 70 mm.

Single phase 240V vs 3-phase motor:

The STH-25 comes with single phase 240V motor as default, or can be fitted with 3-phase motor (415V) for no added cost.

(If wanting 3-phase 415V motor + VFD kit to run on 240V, this costs $1000 more. This is no longer required due to newer single-phase motor but can still be ordered if wanting the option to go to 3-phase power later.) 

Ram weight:

the 25 KG model has a heavier ram and a slower hitting frequency than the STH-15 for more power. The 25 kg is capable of medium weight forging work such as axes and hammers within the max material dimensions of 40 x 40 mm square or 45 mm round bar. In reality the falling weight is closer to 31 kg and capacity closer to 50 mm round bar as of 2025.

About ST Power Hammers:

Many power hammers in China are based on the classic Russian STANKO model, having been developed in the Soviet Union and then advanced over many years by several different companies as technology upgrades in materials and processing machinery evolved.

The ST Power hammers are made by a Chinese brand “ST Anyang Power Hammers”, originally started by former employees from a larger power hammer manufacturer callled "“Anyang FP” also based in Anyang, China. After a difficult start arguing with Anyang FP about copying their copy of the STANKO, the ST Power hammers now marketed are the Advanced series developed by ST and not the standard “Economy” model initially made.

Being a smaller manufacturer the ST Power Hammer company has been able to rapidly upgrade their model range, and today offer a series of advantages over the old model:

• Heavier cast frames by 8-10% for increased strength and reduced vibration
• Single-piece cast piston for longer life and less wear
• Steel bushing rather than copper on connecting rod for improved working life
• More robust oiler for consistent lubrication with less need for adjustments
