V-MAX
Our goal with V-Max was to develop a universal bar stock that would provide the most useful properties at the most economical price - an effective but simple general purpose material that would stand up under the most adverse conditions. V-Max was developed from the chemical model of a 1330 steel, which was subsequently micro-alloyed using the most advanced processing. BENEFITS OF V-MAX
Dollar for dollar V-Max may be the best general purpose bar stock value in North America.
V-Max is a new bar product developed by a revolutionary processing technique, designed to refine and purify the alloying matrix. This process yields a universal shafting material ideal for both maintenance and manufacturing needs.
This product is botheasy to machine and easy to weld. Because it is strong, versatile and economical you will find yourself using V-Max for a good portion of your general maintenance needs.
V-Max will save you time, energy, duplicated inventories and headaches. It is an indispensable item in the tool room, machine shop and production inventories.
FEATURES OF V-MAX
- Strength
- Ease of machining... not gummy or mushy
- Ease of welding and repair
- Economical
- Will take and hold a bright finish
- Availability and continuance of supply
- Quality assurance
- Comprehensive size range
- Durable ... resists twist, bow and fatigue
- High impact values
- Resists creep at higher temperatures
- Resists deformation or "walking" during machining due to accurate stress relieving at mill
APPLICATIONS
V-Max can be used for a variety of shaft applications in the following industries:
- Industrial machine shops
- Machine tool manufacturers
- Heavy equipment and machinery manufacturers
- Fan, pump and compressor manufacturers
- Maintenance departments
- Tool rooms
- Cement plants, steel mills, mines, pulp and paper
- Power plants, refineries, sand and gravel and aggregate processors, grain and fertilizer plants

Machining and Altering V-Max
Case Hardening
Responds well to flame, induction, Carburizing, or Nitriding methods of case hardening. Typical surface hardness by flame or induction is 50RC.
Note: V-Max is furnished at a hardness considered to be optimum for most general purpose applications (approx. 230 BHN). Although subsequent hardening is easily achieved, most applications will not require it. Subsequent hardening will alter physical properties and surface finish. Should your particular application require higher specific properties or should you need something other than a general purpose grade of shafting material, please inquire with your Baldwin representative and/or review other Baldwin bar products.
