Both AISI 304 stainless steel and ASTM A36 carbon steel are iron alloys. They have 71% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
The American Iron and Steel Institute (AISI) and the American Society for Testing and Materials (ASTM) are industry standards for iron and stee manufacturing and grading. While both are concerned with iron and steel, these agencies have a lot of differences. One is that AISI is a North American association while ASTM is an international one.

AISI 8620 Steel is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as rolled condition with a maximum hardness HB 255max. SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant.
Alloy steel is steel alloyed with a variety of elements in total amounts of between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels.
AISI 304 is a guideline/reference only and does not give minimum or maximum values regarding physical properties. SS304 when tested as per specification refers to different standards of ASTM, BS etc. according to the nature of material being teste, difference between astm a304 and aisi 8620

8620 is quite popular for carburization, so I don't see your problem with afterwards carburization process. But 8620 typicall has 0.5% Ni vs. 2.0% of 43XX. Ni will give you excellent impact toughness. So maybe you won't have enough toughness, unless currently you have plenty to cut down.
Alloy steels comprise a variety of steels whose compositions exceed the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B, which have been fixed for carbon steels. These steels are more responsive to mechanical and heat treatments than carbon steels. The following datasheet will provide details about AISI 8620H alloy steel. Chemical Composition
We supply a lots of 4130 and 4340 steel grades to our customers all over the world. You will find the chemical and mechanical properties comparison between steel 4130 vs 4340 steel grades as below.
8620 is a low alloy case hardening steel which is supplied to American standard SAE 8620 and AISI 8620. 8620 can be carburised, which will achieve a tough core with a hard wear resistant case. 8620 provides a combination of toughness and wear resistance. 8620 is supplied in either the as rolled or annealed condition for subsequent case hardening.
ASTM License Agreement Withdrawn Rationale: This specification covers cold-finished alloy steel bars of grades and cross sections regarded as generally suitable for heat treatment, for machining into components, or for use in the "as-finished" condition in constructional applications, or for other similar purposes.

ASTM A304 is a specification document for multiple grades of carbon steel. It doesn't include SS. ASTM A240 is a specification for multiple grades of SS plate, strip, and sheet for instance and includes 304 or UNS S30400. 304 fasteners are under ASTM A193 and are identified as "B8". Cold working is a variable to be aware of.
Case Hardening Steel Bar 8620H Colour code: Red (Band) - White Introduction Atlas 8620H is a low Nickel Chromium Molybdenum case hardening steel of medium hardenability used principally for relatively lightly stressed components. Atlas 8620H can be carburised and subsequently hardened by a quenching and tempering operation. The
AISI 8620H is a common, carburizing alloy steel used for a variety of medium-strength applications including gears, camshafts, fasteners, and chains/chain pins. Flexibility in hardening treatments allow optimization of case/core properties.

8620 is the ASTM grade. That number tells you what the major chemical components are and in what percentages. 8620 is heat treatable by carbon steel used for many different applicatons. Anonymous 1 decade ago

ASTM, on the other hand, is a body that defines "standardized" testing so that what one manufacturer calls "304 stainless" is the same material (chemically and physically) as everybody else's "304 stainless". See the "blurbs" on each below. ~ * ~ * ~ The American Iron and Steel Institute (AISI) is an association of North American steel producers.
Alloy steel contains alloying elements such as aluminum, chromium, copper, titanium, nickel, silicon and manganese in varying amounts to manipulate the properties of steel such as weldability, strength, formability, hardenability and corrosion resistance. AISI 4320H is a nickel-chromium-molybdenum steel.
Comparison of the as-received steels (Table 1) with carburized steels (Table 2) showed that the ASTM grain size for AISI 8620 was essentially the same both before and after carburizing and conventionally quenching (ASTM 10 and 9.5, respectively). However, there was a significant difference in ASTM grain sizes observed before and after , difference between astm a304 and aisi 8620
