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 both easy 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.

Heat Treatment

Hardening 1725°F
Annealing 1400-1450°F
Tempering 1600°F
32-34 RC 900°F
35-40 RC 700°F
Quench in oil (130-160°F) or warm water.
Hardness results will vary with size and actual ladle chemistry.

GRADE
TYPE PERCENT MACHINABILITY (1212=100%) WELDABILITY DESCRIPTION

1018

1020

Low Carbon CD or TG&P 78 GOOD General purpose, low strength, gummy or mushy to machine, dull finish, doesn't thread well, good case hardening
1045 Medium Carbon CD or TG&P 57 POOR Higher strength than 1018 but higher carbon makes welding difficult
1144 Medium Carbon CD or TG&P 76 POOR Resulfurized, free machining, difficult to weld
Stress-Proof (1144) Medium Carbon CD or TG&P 83 POOR Good machinability (a modified 1144) with higher strength
V-Max Lower Carbon Micro-Alloy TG&P 80 GOOD
Easy to machine*, holds bright close tolerance finish, threads well, excellent case hardening

*MACHINING: Machine as a low carbon steel. Adjust settings as you become more familiar with this product.
