Dear iceclass1994, Component looks like made by pressing (shearing a sheet)an as rolled sheet. Looks like not heat treated as the hardness was only 90HRB. Used as hand tool in mining applications for clamping and unclamping threads of a pipe. Al: 0.023, Ti: 0.006, Nb: 0.001 This is a part of...

I have a specification asking for Inclusion requirement as 'Slags type D > 20 my must be < 0,3 particles/cm2'. This requirement is in addition to other requirements of Type A,B,C,D in thin and heavy series. I could not understand what exactly it means. Can any one help me with this. Your help...

Dear All, I have analysed a steel material and found the following chemistry. Can any body help me in identifying this steel? C: 0.17 Si: 0.05 Mn:0.86 S:0.004 P:0.014 Ni:0.12 Cr:0.11 Mo:0.04 V:0.003 Cu:0.39 Your help is highly appreciable.

Hi All, Plese see the chemical composition of this material fiven below. C: 0.45-.50 Mn:0.6-0.9 Si: 0.15-0.30 Cr: 0.90-1.20 Ni: 0.40-0.70 Mo: 0.90-1.10 V: 0.10-0.15 S:0.025 max P: 0.025 max

Hi All, What are the other equivalent standards for 388K? Is this material forgeable? Recently I forged this steel and ended up with cracks in some of the parts. I would appreciate if any of you can help.

Dear All, Can any body suggest a procedure for carbon burnout in Pit type of furnaces?

Dear TVP, If I have good heat exchanger can I reduce the ration to 1:8?

What should be the oil (in litre) to batch weight (in kgs) ratio maintained in quenching. Is it 10:1 or 8:1?

Dear All, I have been trying to find out a good source for learning more about hard facing using WC (cast carbide and sintered carbide) metal composites. I would appreciate if I can get the details of a suitable source to learn more about these material and application.

Dear All, I have employed Methanol+Acetone system for generating carbon potential (CP) inside the furnace for carburizing. Methanol is used for generating base level CP (0.4) and Acetone for enriching (1.0). I follow is boost+diffusion cycle (50%+50%). Methanol feeding starts as 750 deg. C at a...

Dear All, I am trying to establish carburizing process using Methanol+Acetone for carburizing atmosphere generation inside the furnace. I am facing a peculiar problem of air bubble getting entrapped in to the flow line which intern obstruct the free flow of Acetone. Because of this I am unable...

I carburise the material (EN36 C and AISI 9313) at 920 deg C. and cool it to 700 deg. C in the furnace and unload to cool it to room temperature in air. After this the material taken up for hardening and tempering. I want to know is there any specific time interval within which the hardening...

Can SAE AMS 6418 material be carburised? I am trying to carburise to increase the surface hardness to 55HRC.

HI Metngr, The application is in rotary tools and percussion bits. The material should withstand high fatigue application.

Hi All, I have been using materials with Nickel as main alloying elements like AISI 9313, 8720, 4815 etc. All these are carburising steels. In the last one year due to increase in Nikel prices in the international market (15,000 USD to 33,000 USD per ton) the prices of steel is increased by...

Hi TVP, When I said A410 it is AISI 410. The chemical composition is C: 0.15 Max, Mn: 0.5 - 1.0 Max. Si: 0.5-1.0 Cr: 11.5-13.5 S: 0.03Max. P: 0.04Max.

Is there any relation between charpy and izod impact values? When to use Charpy and when to use Izod test?

What is the comparison between Fused WC (Tungstun carbide) Vs Sintered WC?

What is the cycle to be followed for carburising of A410 to get case depth of 1.0-1.2mm case depth.

I have been hardening the case carburised material by reheating from room temperature to hardening temperature after carburisation process for materials like 8720, 9313, 4718 etc. Now I am planning hardening by bringing down the temperature to hardening temperature from carburising temperature...
