Bandsaw Cutting and Grinding Superalloys

Posted by Jeff Kirchner on Nov 26, 2017 9:59:11 AM

Bandsaw Cutting Superalloys

When band sawing softer alloys, the more economical high speed steel blades can be utilized. The machine must be set up to cut at much slower speeds to use the high speed steels. Some equipment does not have the capability to slow feed or speed as much as needed. Blades that are 1.5-2" wide or wider are recommended to provide a rigid set up.

Tungsten carbide blades can be utilized and can cut much faster, the trade off will be the number of cuts per hour vs. the higher cost of the blade. Tungsten  Carbide tipped blades are  required when cutting material   with hardness over Rc 37.

Blade manufacturers sucessfully used:

  1. Lenox
  2. Simonds
  3. Bahco

TOP 10 TIPS  to  Make Good Metals Purchases

Posted by Jeff Kirchner on Nov 21, 2017 9:57:00 AM

This is a guide to help to buyers  always get the the best price on metals.  Most metals buyers employ one of these tips, but many of these can be used in the process of buying - all at the same time.

10.)  Buy in bulk - our materials do not have an expiration date. Standards may be updated over the course of several years, but we will work to update certifications upon request.

MACHINING DATA FOR NITRONIC®

Based on 1" Dia Annealed (RB 95) 5 hour form tool life using high-speed tools. Carbide tools are suggested, for rates better than 50% of Type 304. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Type C-3 for finishing.

Corrosion Resistance

Armco NITRONIC 50 Stainless Steel provides outstanding corrosion resistance - superior to Types 316, 316L, 317 and 317L in many media. For many applications the 1950 F (1066 C) annealed condition provides adequate corrosion resistance and a higher strength level. In very corrosive media or where material is to be used in the as-welded condition, the 2050 F (1121 C) annealed condition should be specified. High-Strength (HS) NITRONIC 50 bars are useful for applications such as shafting and bolting, but do not quite exhibit the corrosion resistance of the annealed conditions in all environments.

AMS 5894

Wear Resistant (Co-Cr-W)

Cobalt 6B is a cobalt based chromium, tungsten alloy for wear environments where seizing, galling and abrasion are present. 6B is resistant to seizing and galling and with its low coefficient of friction, allows sliding contact with other metals without damage by metal pick up in many cases. Seizing and galling can be minimized in applications without lubrication or where lubrication is impractical. Metal seizing is similar to one metal piece building heat against another and they become "welded" together. Galling is when these "weld" areas break off and form an abrasive debris which creates additional abrasion problems.

New qualification received

Posted by Jeff Kirchner on Nov 2, 2017 8:23:00 AM

We have made the list of qualified vendors for SpaceX. Both facilities, Windfall and Tipton are on the Falcon 9 approved vendors list. We are very excited about all the new work that SpaceX is taking on to facilitate travel to the ISS (International Space Station) as well as many other launches to come.

Manufacturing highlight: Mechanical property enhancement through the use of grain refinement

Posted by Jeff Kirchner on Feb 10, 2017 2:05:00 PM

Grain refinement

There are many applications that can benefit from grain refinement. Grain refinement is a result of specific manufacturing techniques which allow for a finer grain. In almost every case, a finer grain material will outperform a coarser grain item of the same material. The basis of finer grains being stronger is that while there are more dislocations in the material, it is more difficult to make all these dislocations line up. Finer grains also typically have less precipitates in the boundaries. Precipitates are oxides, carbon, and interstitial elements that are not in solution of the grain. Precipitates are normally not as strong as the material itself - tending to make a precipitated material more brittle.
