ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

“Oh that my child be godly. Oh that my child give it all for the sake of Christ. Oh that my child live for Him. Oh that my child not be enslaved to the very things that so enslave me.
Do you realize, now listen to this, there’s a balance in everything, there is… but do you realize that if you would just take an agenda/write down a list of how much time you invest in your children in extra curricular activities (versus) how much time you invest in your children with regard to godliness.
We buy things, we fill them full of media, we put them in the world, and we carry them every place on the face of the earth all throughout the week that our lives are so busy and scattered that we can’t even sit a meal and what are we doing?! We’re making our children enslaved to the very master that enslaves us and ruins our lives instead of teaching our children only one thing is needed: devotion to Christ.”
- Paul Washer
“No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money. “Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing? Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? And which of you by being anxious can add a single hour to his span of life? And why are you anxious about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin, yet I tell you, even Solomon in all his glory was not arrayed like one of these. But if God so clothes the grass of the field, which today is alive and tomorrow is thrown into the oven, will he not much more clothe you, O you of little faith? Therefore do not be anxious, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For the Gentiles seek after all these things, and your heavenly Father knows that you need them all. But seek first the kingdom of God and his righteousness, and all these things will be added to you. “Therefore do not be anxious about tomorrow, for tomorrow will be anxious for itself. Sufficient for the day is its own trouble.”
- Jesus Christ
(Mat 6:24-34)
