I'm looking for recommendations for an alternative to ASTM A487 Gr 10B.
A487 is for Pressure Service castings and requires a lot of heat treating to process.
Many years ago, our Metallurgist, who has since passed, selected this material to cast hammer heads out of.
We hadn't made any of these...
Recently my check gages light has been coming on, and when I looked the oil pressure was dropping to almost zero.
This only happens when I come to a stop and the engine is up to temp.
This also seems to happen only when I've been running the AC.
Putting the trans in to neutral and a quick tap of...

I had this posted over at the gear and pulley group, but didn't get any replies so I thought I'd try this group.
I'm looking for a full strength rated connecting link for 3/8" Grade 100 chain...
I'm looking for a full strength rated connecting link for 3/8" Grade 100 chain that will fit in the pockets of this chain wheel.
This is for a close loop system for moving carts though an assembly line.
I'm making the drive with the chain wheel and the customer is somehow making the connection...
Due to the on-going supply chain issues, I am looking at using a brand of wire rope block that I am not familiar with.
The company I am going get it from is one I've worked with for many years, but I wanted to get others thoughts on the brand.
The brand is called "RopeBlock" out of the...
I've sort of stumbled into a new market for one of our stock product lines.
I'm using our small capstan by removing the smooth rope barrel and replacing it with a chain pocket wheel for 3/8" chain.
The end users do not have a lot of details regarding the chain they've been using but the samples...
I am working on automating a winching system to load open top hopper railcars from an overhead conveyor.
This will need to sense that the cars are in position to be loaded then advance as the product reaches a certain height above the top of the car.
This particular project will involve 7 cars...
I'm looking for a wrought steel equivalent to use for a forging in leu of ASTM A757 Gr. C1Q.
We will be making rectangular blocks up to 12" thick.
One thought was to make C1Q blocks and then forge them to shape.
Any input would be greatly appreciated.
Best regards, David

We have a very large casting in house (ASTM A757 Gr C1Q) that has Lab confirmed Aluminum Nitride Embrittlement.
The last post in the linked thread stated that Re-Austentizing could often remedy this condition.
My question is how reliable is this process.
The casting is mostly a...
We have a Miller Pro heat 35 with the liquid cooling for PWHT and so far we love it.
Most of the time we can warp the induction cable around the part even if it's not a true pipe or can wrap it in a flat coil as long as it is on a horizontal surface or we can drape it over the part.
We are...
I am getting ready to try and sell a home and I have the typical rust "barnacles" on the drain stack in the basement.
I have had a couple of plumbers in for different things and when I bring up replacing the stack they keep trying to tell me that if I replace the stack I'll have to bring a bunch...
We are in the process of qualifying a weld procedure for 5086 Aluminum using 5556 filler wire and we are getting lots of porosity using the MIG process.
The plate is 1/2" thick, the weld joint is a "V" groove, wire is 3/64 (.047) diameter.
We have success with TIG on the same base material...
I am looking for reference materials and/or pointers for a casting a steel part that incorporates a precast stainless steel component.
I have seen bronze gears cast around a steel hub.
The stainless steel would be shaped like a shell of the inside of a toroidal field (dough nut hole)
The steel...
I am currently working on a WPS and qualification for ASTM A757 GR C1Q castings but now a project has come up that would require A1Q.
My current wire is E81T1-Ni1.
Other that a slight overage on tensile and a 300F preheat vs 50F, would there an problems with using the WPS for both grades of...
Not too long ago I supplied a machine to an ocean going ship and I have received some feedback that the aluminum handles on the control valves are not doing very well.
I used valves from a fairly well known mobile hydraulic valve manufacturer.
I spoke with the company and was informed that the...
I have a home Furnas from the 1950's take is in very good shape and works well but I would like to upgrade it with a current style automatic pilot safety valve.
Is that something a typical HVAC contractor can do you would it require someone with a special License?
I've lived in the house for 25...
I am working on a welding procedure and the welding expert said that we should prepare the test plates with the "Grain" of plate a certain direction.
One of the testing labs I work with told me to use a solution of HNO3 and 98% Ethanol but finding small amount required is becoming complicated...
I am working on a DOD project that one of the material call outs is ASTM A575 Mechant Grade steel.
My main problem with this specification is that the size of round stock I need not readly available.
What I am looking for is an ASTM or governemt document that states that material per ASTM A576...
I am looking for chemistry and heat treating information for a cast version of Inconel 693.
Some of the research I have done for some of the other Inconel 6XX series has lead me to ASTM A494.
I have data that lists the chemistry of Inconel 693, but I'm not sure that just matching chemistry is...
I am working on a project that has cast Hadfield manganese steel (ASTM A128 Gr. A) parts.
One of the main properties required is that the magnetic permeability needs to be less than 1.2mu.
The foundry that is casting the parts for me has experience with casting Hadfield for wear resistant parts...
