Introducing Nickel Chromoly – A new material with so much additional ball speed, our engineers switched their focus to feel and stopping power. At 35% stronger than our original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface. Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long. The Pro model is more compact, with minimal offset for confident ball-strikers seeking maximum ball speed.
TECHNICAL DETAILS
Harmonic Impact Technology: Fine tuned head geometry delivers ideal impact feel and feedback
Seamless Cup Face: Thinned areas revolving 360 degrees around the perimeter increase rebound area for maximum ball speed across the entire face
CORTECH Design: Optimized face thickness distribution to maximize COR AREA
Variable Sole Thickness: Increase overall face flex area for add CORAREA
Acoustic Sound Ribs: Precisely dial in specific vibration patterns for a solid, explosive impact sound
Beveled Trailing Edge: Aggressive relief on the trailing edge for reduced turf drag
4335 Nickel Chromoly: 4335 Nickel Chromoly is 20% stronger, allowing for an 8% reduction in face thickness, resulting in higher ball speeds.
V-Chassis: Engineered via Mizuno's Harmonic Impact Technology, the V-Chassis allows the top line to be thinner without sacrificing feel and sound.
White Satin Brush Finish: A modern elegant, yet durable non-glare finish
Compact, with minimal offset for confident ball-strikers seeking maximum ball speed.

Introducing Nickel Chromoly
A new material with so much additional ball speed, our engineers switched their focus to feel and stopping power.
35% stronger than our original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface.
Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long.
JPX923 Hot Metals Overview
FASTER NICKEL CHROMOLY
New 4335 Nickel Chromoly is 35% stronger than our original Chromoly, for an 8% thinner, high ball speed clubface.
V-CHASSIS FOR MORE SOLID FEEL
Mizuno’s new V-Chassis delivers a more solid satisfying vibration pattern, even though the clubface is 8% thinner.
Increased Stopping Power
Seamless cup face construction delivers the deep centre of gravity needed for a high launch and controllable landing angle.
CONSISTENT BALL SPEEDS ACROSS THE FACE
The thinnest part of the sole is extended 18% wider, creating a wider high-energy area.
WHITE-SATIN BRUSH
Non-reflective, Chrome plated finish to reduce bright light glare.
175,000 real golf swings recorded via Mizuno’s Swing DNA system every year highlighted the need for variable launch options.
