The difference between performance of 89c51 and 89s51 is that the 89c51 has a standard 51 core. The 89c51 program cannot be directly ported to 51 compared to the 89s51.

NACE MR0175 is a standard for sulfide stress cracking resistance in oil and gas industry equipment. A105 is a common carbon steel material used for flanges and fittings. Fitting NACE material A105 would mean that the A105 material meets the requirements specified in NACE MR0175 for sulfide stress cracking resistance.
A106 is for pipes and A234 is for Fittings, as well as A105 are for forgings.
Vessels are made up of plate materials. A106 is a pipe destination. A105 is a forged material and widely used for flange

the answer is 304
Nothing there both the same
ASTM A105 refers to a standard specification for carbon steel forged fittings, flanges, and valves for use in piping systems at room temperature and higher. A105 NACE, on the other hand, includes additional requirements to meet the NACE MR0175/ISO 15156 standard, which addresses the material's resistance to sulfide stress cracking in sour service environments. Essentially, A105 NACE is designed for applications where the material may be exposed to hydrogen sulfide, enhancing its corrosion resistance compared to standard A105.

Simply, A105 is an ASTM standard for a ratedsteel where SA105 is the ASME standard for (nominally the same) rated steel. Basically, they are the same, although SA105 has additional applications beyond A105 according to ASME standards.
ASTM A105N is different from A105. The A105 is classed "as forged" as opposed to A105N where the 'N' stands for normalized i.e. it has been heat treated to remove the internal stresses caused by casting, forming etc. If a customer specifically asks for A105N then it will be for a good reason. The normalizing heat treatment will ensure the A105N has superior properties to that of the A105. The 'N' is not a category code, the A105 should be normalized if intended for use below -1 C. There are API regulations that go further into it that you should read up on, primarily API RP14E. Hope this helps
yes, we can use A105 instead of WCB. WCB is the casting grade while the A105 is equivalent forged grade.
