    Would an OES and hardness test be sufficient?

    Hi mrfailure, Thanks. I responded back to an Italian laboratory just now. Providing some more information to them for a quote. For #1, the panhard mounting point, I'm tempted to bet on 4130 as a replacement to save cost. I've asked them if they can check if sample #1 has received a heat...

    Would an OES and hardness test be sufficient?

    It is for a critical car part. I don't want to risk making assumptions about the steel. I do believe EdStainless is right in his advice to me. Furthermore I don't like you being so terse in your communication. Was that $800-$1000 estimate what it could cost me for a full analysis of these two...

    Would an OES and hardness test be sufficient?

    Sorry I don't know what you mean. You mean abandon the chemical analysis altogether? What is meant by "buy a minimum length" for example?

    Would an OES and hardness test be sufficient?

    Hi mfgenggear, What should that cost me approximately? I'm an automotive hobbyist from Europe. Sample #1 is round rod with diameter of 18mm and length of 30mm. Sample #2 is round tube OD 25.4mm and wall thickness of 2.7mm and length of 73mm. I don't care about coating I will grind that off...

    Would an OES and hardness test be sufficient?

    I'm also very much interested in this. What should I be able expect from a laboratory. Would a proper OES be able to specify all the elements in the steel to two decimal places? Also carbon and sulfur. Weight percentages are the usual specification, do they? What is shown at McMaster-Carr...

    Would an OES and hardness test be sufficient?

    Thanks Ed! Much appreciated. With that last bit "nothing else does." You mean the other properties like elongation and toughness, do you?

    Would an OES and hardness test be sufficient?

    I need to determine if a unknown steel sample has received a heat treatment or not. So I'm advised by someone on another forum to have a laboratory perform an chemical composition analysis. I do think an Optical Emission Spectrometer (OES) analysis would be the most suitable because it is...

    Hardness Tester File Set

    Hi there, Regarding an automotive modification project I would like to test if some steel pieces would have been heat treated or not. Apart from this I plan to have a lab do an XRF analysis as well to find the material composition. Someone on another forum suggested me a Hardness Tester File...

    Mitigate strength reduction when welding after heat treatment

    Hi MintJulep, Yes, it is actually that Whiteline product that you shown. The model number is KPR020 and they stated that it is applicable to P9 Starlet cars. Which include my EP91 model from 1997. I've read on a Starlet forum how people who bought the KPR020 rod deal with having insufficient...

    Mitigate strength reduction when welding after heat treatment

    The design it not different than what Toyota made. I just need to copy Toyota's design with a few other dimensions. The industrial revolution would not have happened if people shy away from each and every challenge. With my own research I learned for example that I do need to stress relieve the...

    Mitigate strength reduction when welding after heat treatment

    That performance panhard rod came with an 6mm extension ring to be put on this shaft. But securing the bushing with two washers on both ends and a nut will only have a few threads engaged on the threaded end. Not something I want to rely on for a car. I prefer to design a new shaft for this. I...

    Mitigate strength reduction when welding after heat treatment

    Hi there, I'm new to this forum. I am a DIY mechanic who also has an interest in metalworking. I hope my topic is interesting enough for this forum. As it is primary used for professionals sharing knowledge on work projects. Alright this is the rear axle beam on my 905 kg, FWD car. A 1997...
